摘要
在软弱地基中采用土钉墙基坑支护结构,当基坑开挖到一定深度时,由于地基自立性差或承载力低而受到一定限制,工程中通常采用超前锚杆来提高地基土的承载能力。土钉墙设计中,应从超前锚杆与地基土的相互作用机理出发,分析超前锚杆在土钉基坑支护中的工作机理,研究超前锚杆在土钉支护中的稳定性分析方法。
The soil-nail wall support of foundation pit adopted in soft ground is linited by the excavation dept of the pit due to the poor self-stability or low load-capacity of the ground. Leading anchor is usually used to improve the ground load-capacity in the engineering. In the design of the soil-nail wall, we should begin with the interacting mechanism of the leading anchor and the ground soil, then analyze the functioning mechanism of, and research the method for analyzing the stability of, the leading anchor in the soil-nail support of the pit.
