摘要
城市建设的高速发展和地下空间的充分利用,促进了深基坑的发展,由此带来了大量的深基坑开挖和支护的岩土工程问题,尤其是软土基坑。在软土基坑中设置锚拉桩,能有效地控制支护结构与土体的变形,同时有利于基坑土方的开挖和主体地下室的施工,显示其十分突出的优势。介绍了锚拉桩支护结构的计算模式,并对相应工程的监测结果进行了分析与比较,取得了较为满意的结果。
Speedy development of city buildings and full use of subterranean space have accelerated the development of deep foundation pits; and that have also brought a mass of geotechnical engineering problems, such as soft soil foundation pits. When the anchor piles are adopted for a foundation fit, displacement of the retaining structure and soil can be controlled effectively; and it is propitious to excavation of earth, showing the extrusive active purpose. A kind of calculation models for anchor piles brace structure is described emphatically; and quite satisfied results are obtained via a comparison and analysis of specific monitoring.
