支护是对基坑进行支撑和保护的结构。是保证施工安全顺利进行所必须的保护措施。在支护结构的设计中需要考虑到土体沉降、基坑变形的问题,并且确保在基坑施工中能够确保周遭建筑物和管件的安全。还需要顾虑到支护结构的经济,实用,整个支护结构不尽要起到保护作用,结构的设计也不能影响到施工的进行。这边要求设计人员在对支护结构进行设计时,需要将一切问题考虑到设计方案中。
Support is the structure that supports and protects the foundation pit. Is to ensure the smooth construction of the necessary protective measures. In the design of retaining structure, the settlement of soil mass and deformation of foundation pit need to be considered, and the safety of surrounding buildings and pipe fittings should be ensured in the construction of foundation pit. Also need to take into account the support structure of the economy and practical, the entire support structure does not play a protective role, structural design can not affect the construction. This requires designers to design supporting structures need to consider all the issues into the design.
