摘要
相邻或盆式开挖深基坑施工时,基坑内侧或外侧的预留土堤应作为深基坑设计因素而予以考虑。基坑预留土堤土压力与它的形状及围护结构等因素相关。场地条件许可时,应采用原状土预留土堤,可用库仑土压力理论分析。当采用加固土预留土堤时,可采用抗侧刚度分配法分析。预留土堤规模及土压力可以通过计算机分析实现,也可采用图解法分析。
When adjacent deep pit excavation or basin excavation is under construction, the provided mud dyke inside or outside a pit should be considered by design. The earth pressure of a provided mud dyke is related to its shape and pit supporting structure. When a construction site is open enough, an original state mud dyke should be adopted and analyzed with the Coulomb Theory. When a prestressed mud dyke is adopted, it could be analyzed with the shear stiffness allotting method. Analysis of a provided mud dyke can be carried out by means of computer program or diagrammatically.
