摘要
本文主要介绍地下室范围主要土层为砂层,且地下水位比较高的情况下的基坑支护设计。分别比较了降水方案和截水方案的优缺点。本工程透水砂层厚度达14m,截水方案针对砂层比较厚的情况采用三轴深层搅拌桩止水帷幕,截水深度18m,起到良好的截水效果。根据场地周边不同的场地条件合理采SMW工法支护及土钉结合深层搅拌桩复合支护达到经济又安全的效果。
This paper mainly introduces the basement mainly for sand soil, and the underground water level is high in the case. of foundation pit support design. Compare the advantages and disadvantages of precipitation and water interception scheme. The permeable sand thickness up to 14m, water interocption scheme for the sand thick by three axis of deep mixing pile water stop curtain, water depth 18m, play a good interception effect. According to the mining and reasona- ble SMW method venues surrounding the different site conditions and soil nailing support combining with deep mixing pile composite supporting to achieve the effect of eeonomy and safety.
