Using self―made model device, researchers studied the characteristics of foundation settlement of sandy soil and pile foundation load―bearing in sandy soil. Through weight loading, researchers analyzed the phenomenon of foundation settlement. Then, researchers embedded friction piles in sand, so as to analyzed pile foundation bearing capacity. The methods and results of the research can provide guidance for teaching of Soil mechanics and foundation engineering.

Bored Pile

A viaduct of the Qinglai expressway fourth contract was artificial excavated piles. The construction technical work was regarded as an example. The technical comparison were done between the artificial excavated pile and the bored pile on the pile foundation bearing capacity and the retaining wall effect . The artificial excavated pile replacing the bored pile was feasible, and the construction technology and the key problems of the artificial excavated piles were confirmed. The references were provided to the similar projects.

The article discusses issues related to the construction of pile foundations of buildings and structures, including bridges and other transport facilities. The development of the construction industry contributes to the improvement of pile Foundation construction technology and a significant reduction in economic costs. Improving the design and technology of pile foundations is one of the main tasks in the field of transport construction. The effectiveness of pile foundations is due to the more complete use of the bearing capacity of the soil base and the strength of the Foundation elements. One of the disadvantages of the pile foundation is the low bearing capacity of the soil on the side surface of the pile. The proposed solution is based on the device along the longitudinal axis of the pile rigidly fixed, multi-pass continuous inclined edges having the shape of a plate, and faces adjacent to the side surface of the tubular steel barrel.
