高水位砂土地区深基坑支护结构工程设计

Engineering design of supporting structure of deep foundation pit in high level water and sand soil area

基坑的开挖在很大程度上受土质和地下水位的影响。在高水位砂土地区基坑设计中所采用的水泥土搅拌桩结合灌注桩基坑支护的方法,通过改善土体性质,提高土层的力学性能,从而对基坑起到支护作用,有效地防止地下水的影响。

The soil properties and underground water level affect the excavation of foundation pit to a great extent.The appliance of cement mixed pile combined with pour pile foundation pit supporting is a good way to improve the soil properties, and enhance the mechanical properties of the sludge, so as to protect the foundation pit against the affect of underground water.
