地下室复杂基础施工技术研究

对于常规桩筏基础而言,在连接桩和筏时主要采取刚性连接的方式,并由筏板和桩基础支承的刚度来决定其整体刚度。为了有效满足经济和施工等方面的要求,需要对桩筏基础刚度进行调整,具体可以采用变形调节装置来对桩筏支承刚度进行调整和优化。

For conventional piled raft foundations,rigid connection is the main way to connect piles and rafts,and the stiffness of raft and pile foundation is used to determine the whole stiffness.In order to effectively meet the requirements of economy and construction,it is necessary to adjust the stiffness of pile-raft foundation.Specifically,the deformation adjusting device can be used to adjust and optimize the supporting stiffness of pile-raft.
