The geomorphology of «Protopopovskiy» landslide in the valley of the Oka river (in the city of Kolomna, Moscow region)

This article is devoted to the development of the slope processes in the Oka river valley in the city of Kolomna. There are considered the modern ecological and engineering-geological condition of floodplain terraces in the city quarter of Kolychevo. The aim of the work was to study the geomorphology of landslide processes. There is considered the identification of the causes of landslides in the Oka river valley. The is considered the identification of representatives of fossil fauna of organogenic limestones of the left Bank of the Oka river to. In this paper, for the first time the «Protopopovskiy» landslide is described in the scientific literature.

Scientific Site Selection of Ancient Large-scale Underground Quarries from Engineering Geology: A Case of Shepan Island in Sanmen, China

There are many ancient underground quarries in Zhejiang Province, China. Many caverns of them maintained steady more than 1000 years. Certain engineering geological condition is very important for long-term stability. In this paper, ancient underground quarries in Shepan Island are presented as a case. Shepan Island ancient large-scale underground quarry caverns are located in Sanmen County, Zhejiang Province. These caverns were excavated more than 800 years ago and at least 1300 of them are reserved until now. Shepan Island is a hill which uplifts the continental shelf extending to the gulf. There are no large regional fractures through caverns area, which indicates that it belongs to earthquake stability region. The caverns were excavated in thick volcanic clastic rock formed in the upper Jurassic, with NW and NE faults and NW joints. Based on the study of rock weathering, physical and mechanical tests of rock samples, and inverse analysis of structural plane, the huge thick volcano clastic rock can be classified as block structure. In addition, groundwater which affects the stability of caverns was analyzed based on the investigations of hydrogeological conditions. Site selection of ancient large-scale underground quarries is query scientific from modern engineering geology point of view.

The Stack Soil Management for Construction Site

The topography, hydrogeological condition and engineering geological condition of various regions are complicated in China. The demolition and site preparation of mountains construction site generally need to do a large number of excavation and embankment fill, need to consider the problem such as landslide and slope, temporary earthwork stack. The available soil temporary stack involving the question such as safety, environmental protection, etc, with two instances to illustrate should according to quality, safety and environmental protection objectives for construction management of temporary pile soil.

Analysis of the Potential of Seismic Stability for the Southern Region of Tangshan Based on ArcGIS

To assess the potential of seismic stability for the southern region of Tangshan city, five factors are considered, including fault zones, engineering geological condition, hydrogeology condition, dynamic coefficient and site category. In this paper, the process and digitalization and visualization technology of evaluation method for site seismic stability is proposed based on ArcGIS. The overlay method is automatic realized and the seismic stability potential diagram of Tangshan and its southern region is given, which overcomes the drawback that can't automatic classification of other GIS instruments, then time is greatly saved and the efficiency is improved.

Research on Modeling Technology for Three-Dimension Analysis of Irregular Slope Stability in Surface Mines and its Application

At present, the most direct and extensive research method which in the field of engineering geology and rock soil mechanics is a numerical analysis method .But the numerical analysis method is developing from two-dimensional to three-dimensional . The slope stability not only has something to do with engineering geological condition , but also with the concave and convex extent of the slope. The text tries to present the three-dimensional effect of the slope by the three-dimensional model, and takes the example of Jilinguole 2 strip mine irregular three-dimensional slope, researching the three-dimensional model method of the irregular slope stability by AUTOCAD and ANSYS, founding the FLAC3D.This paper analyzes the stability of the Jilinguole 2 strip mine south slope by numerical simulation analysis.

Excavation Program and Stability Analysis of High-Steep Rock Slope

Aimed to the problem of excavation and stability for a high and steep rocky slope, with the design excavation height of 90.23m, this paper grasped the engineering geological conditions and physical and mechanical properties of rock mass by such following methods as the field engineering geological survey, measuring, drilling sampling and laboratory test. Based on this, a comparative analysis of two different excavation ways was conducted using the large discrete element program-UDEC. The analysis included the stress-strain law and deformation failure trends of the slope when adopting slow excavation and steep excavation respectively. Moreover, the environmental damage caused by the two excavation ways was discussed. The results show that the slope has a better engineering geological condition and stability. In order to avoid disturbing hills and protect the natural environment, the steep excavation way is suggested for excavation and reinforcement of this slope.

Rockmass Stability Analysis of YunYang’s Arch Dam Left Shoulder

Arch dam abutment stability analysis of arch dam design, construction, is the primary problem of operation. From home, outside the related data that appear most, arch dam accident due to abutment instability caused by. On the engineering geological condition is suitable, the arch dam is safe and reliable, economic and reasonable and the broad masses of the people welcomed the dam type. But it must be based on abutment stability based on. Therefore in the arch dam design, there is a need for dam abutment rock mass are detailed and thorough exploration and stability analysis of. This paper adopts the rigid body limit equilibrium method based on arch dam on the left bank of the slide stability analysis and dam abutment stability analysis of arch dam plane, gives the dam safety stability evaluation. A cover of hyperbolic arch dam, the dam height is 163.00m, is a type of buildings. The engineering geological conditions in the dam area is more complex, the existence of multiple faults, joints, fissures, karst cave is developed. Study of a dam on the left abutment stability, reliability and stability of project evaluation is a very important technical and economic significance.

Engineering Geological Condition Analysis of some Beijing Engineering

With the high speed railway construction in our country, the launch of the railway engineering will inevitably lead to all kinds of engineering geological problems, resulting in the construction and operation of landslides, sudden gushing mud, rock blasting and other diseases. So with geological environment and engineering geological conditions of the station tunnel excavation , analysis and evaluate the influence of the engineering geological conditions of the tunnel, put forward the measures and suggestions for the engineering, and provide the basis for tunnel design and construction .
