大规模多层次复杂基坑的合理开挖支护设计

Rational excavation support design of large-scale and multilevel complex foundation pit

以某综合主厂房土方开挖工程为背景,对大规模、多层次复杂基坑的合理开挖支护设计进行了探讨,详细介绍了坡率法与土钉墙、钢板桩支护相结合的分层开挖方式,并阐述了该法的优点,指出合理的降水、排水措施是基坑支护的关键。

Taking earthwork excavation project of a comprehensive powerhouse as an example, this paper discussed the rational excavation support design of multilevel complex foundation pit, introduced in detail the layered excavation method combining with slope ratio method and soil nailing wall, steel slope pile support, and elaborated the advantages of this method, pointed out that the rational precipitation, drainage measures was the key of foundation pit support.
