| Abstract: | Since entering the 1990's,the architectures and buildings of Shanghai have been developed rapidly towards the state of high,great,deep and heavy and thus,the test,research,design,construction and monitoring for the geotechnical engineerings have become the main direction of research for Shanghai geotechnical engineering circle. Foundation pile constuction ,deep pit excavation and well sinking on soft soil foundation all will produce the disturbance and damage on soft soil body. The soft soil body which lost stability and had presented complicate stress and strain process will bring damage to the project at any time. Shanghai geotechnical engineering circle has obtained experience from plenty of engineering accidents and also found out a set of effective measures to solve the difficult technical problems in the aspects of geotechnical engineering and have achieved a lot in Shanghai urban construction as well. The paper,moreover,would like to elaborate and approach to Shanghai common engineering technical problems in the aspects of its principle,calculation and process with the fellows in the same trade. |
