沉井基础是以沉井法施工的地下结构物和深基础的一种型式。沉井的施工方法和沉井的设计计算之间有着直接的关系,应根据场地的工程地质及水文地质资料,结合施工条件决定。沉井下沉施工分为排水下沉、部分不排水下沉和不排水下沉三种。本文就沉井不同的下沉施工方式在设计和施工方面的不同进行了比较。
The caisson foundation is a type of underground structure and deep foundation constructed by the caisson method. There is a direct relationship between the construction method of caisson and the design and calculation of caisson, which should be decided according to the engineering geological and hydrogeological data of the site in combination with the construction conditions. Sunk well sinking construction is divided into drainage sinking, sinking some undrained and undrained sinking three. In this paper, different sinking sunken construction methods in the design and construction of the different were compared.
