| Abstract: | ! Foundation pit project of Zhengda Plaza in Pudong New Area is one of the macro-type deep foundation pit engineerings in soft soil foundation of Shanghai area. By adoping"layered dewatering method for pipe well points linking with light-type vacuum well points ",the problems of drainage, pressure relief and float-resistance have been solved. moreover.it not only have saved the cost but also satisfied the requests for stability of foundation pit bracing structure and the environmental protection. |
