摘要
深基坑工程地层中常会遇到岩面埋深较浅即高岩面的情况,特别是岩石强度较高时,基坑围护结构和土石方开挖施工的难度会增大,导致施工效率降低和成本大增。文中介绍了多个深基坑工程的岩石处理方法,采取设计与施工相结合的手段,大大减少了围护结构和支撑立柱桩入岩施工工作量,并采取了多种爆破方式提高了基坑石方开挖效率,值得类似项目参考。
When the rocks are shallow and hard in deep foundation pit,the retaining and protection structure construction and excavation will becomes difficult and low efficiency and high cost. This paper introduces the processing methods of shallow rock of deep foundation pit projects,to reduces rock workload of soldier pile wall and diaphragm wall and strut column from design and construction. With comprehensive application of various blasting method,rock excavation construction is safety and get high work efficiency. It can be referenced in the similar deep foundation pit project.
