摘要
针对南京某地铁深基坑工程的地层和承压水特性,对全套管咬合桩围护、地下连续墙围护及组合式围护等三种围护方案进行了比选研究,并就推荐方案通过离心模型试验研究其技术可行性。研究表明全套管咬合桩围护结构能较好的适应该地层深基坑工程,同时由于其造价低廉,是一种在类似工程中值得推广的围护结构。
Based on characters of stratum and pressure water of certain metro deep foundation pit in Nanjing, comparison and selection of enclosure structure schemes are accomplished for Benoto occlusive piles, underground continuous wall and combined retaining wall. Through centrifugal model test, the technical feasibility of recommended scheme has been studied in this paper. Research result indicates that Benoto occlusive piles are adaptable to be used to construct such deep foundation pit, and this enclosure structure can be extended to similar project because of its low cost.
