The characteristics of pit foundation in Shanghai are "big, deep, tight, near" in recent years. Based on the tight cooperation between design and construction institutions, a series of new development are achieved. New types of retaining struture are developed for large scale excavation. The deformation control of pit becomes the guiding for the design of pit in sensible environment. Design concept of combination of main structure with temp retaining structure is put into more forms of use.. Forms of the strutting system become diversefied. Round retain structure has been put in practice primarily and its advantages are disclosed. Pit progress has the tendency of that more and more new types of excavation and construction technology are come forth by taking the advantage of advanced design theory, construction technics and analysis method.
