黄河三角洲地区土质大部分为粉质粘土、粉土、粉砂,地基土承载力较低,城市地下水位较高。本文以所承建的东胜石油公司综合楼基坑支护方案为例,介绍在黄河三角洲地区,采用钻孔灌注桩加锚杆加深层搅拌桩止水帷幕进行基坑支护工程的设计施工经验。实践证明,所选定的基坑支护和施工方案是成功的,具有形式简单、受力明确、支护可靠的优点。本工程基坑支护是对黄河三角洲软土条件下深基坑支护形式的一种探索,可供类似工程参考
Most of the Yellow River Delta soil is silty clay, silt, silt, the bearing capacity of the foundation soil is low, the urban groundwater level is higher. In this paper, the construction of Dongsheng Oil Company integrated foundation pit supporting project is taken as an example to introduce the design and construction experience of the foundation pit supporting project with the bored piles and anchor rods deepening mixing curtain waterproofing curtain in the Yellow River Delta . Practice has proved that the selected foundation pit support and construction program is successful, with the simple form, the force is clear, the advantages of reliable support. The project of foundation pit support is a kind of exploration for deep foundation pit support form in soft soil condition of Yellow River Delta, which can be used for reference of similar project
