Actual Stress

The conventional design method of tall building is made the superstructure, foundation and subsoil to three separate forms and calculate independently. This method ignores the interaction of the three parts, which does not conform to the actual stress and deformation of projects. This article describes the mechanism of the interaction of the superstructure, foundation and subsoil, and analyses the effect of the superstructure stiffness changing to the interaction, which provides a theoretical basis for controlling the differential settlement of foundation reasonability and optimizing the structural design.

Factual Data

Civil infrastructure as well as building foundation design depends primarily on the availability and accuracy of soil investigation data. The data from site and laboratory are vital for a safe and economical design for any kind of infrastructure or buildings. This paper describes the use of GIS in processing and presenting factual data of site investigation reports in formats that are meaningful to users especially geotechnical designer. The initial effort is carried out for Perak Tengah District in the State of Perak, Malaysia. In this study the site investigation reports are archived in an appropriate manner so it can be quickly retrieved by user at any time. In the second part, the data are stored in GIS system that can be processed and presented into maps describing some basic important data for designer at various depths. Thus, the data are available at any time and the systems will be a meaningful tool for geotechnical designers.

Building Foundation

Under the various load combination of buildings, the deformation of foundation soil. The size of the deformation directly affects the safety of the buildings. Factors that affect the deformation is mainly the geological structure, such as moisture content, density, soil after being compressed volume smaller feature is the compressibility of soil. Geotechnical engineering is a direction of the development of the civil engineering specialty, test provide necessary parameters for building foundation engineering, geotechnical laboratory for cohesive soil consolidation experiment teaching, make students grasp to determine the quantitative relation between the deformation and load, compression curve and rebound curve drawing, it provide necessary theoretical basis for geological prospecting work, provide necessary parameters for building foundation design, closely integrated theory and practice..

Difficult Issue

Crack prevention of high-rise building foundation is an interesting and difficult issue to engineers. Reasons for the crack are analyzed first. Then, based on project cases, crack control methods of large volume concrete foundation are studied in terms of active part and passive part. Active part includes optimizing design of concrete, optimizing foundation design and improving confining condition. Passive part includes reducing temperature difference and increasing the fracture strength of concrete. Finally, optimum foundation design is emphasized for crack control of large volume concrete foundation.

Building Foundation

This is a case history describing a deep braced excavation in which a fully compensated raft foundation was constructed. The foundation soil is the Victoria marine clay, which is a soft normally consolidated deposit 70–100 ft (21–30 m) thick at this site. Observations were made on the deflections of the bracing and the heave of the excavation and were considered a necessary part of the design. Observations have also been kept on the settlement of the building foundation for over [Formula: see text] years. The calculated safety factors used in bracing design and foundation design are compared against the actual performance.
