摘要

深基坑支护工程中,土钉墙与预应力锚杆的协同作用是保障基坑稳定的关键。土钉墙通过密集布置的土钉与土体形成复合体,增强土体抗剪强度,而预应力锚杆则通过锚固力提供额外的抗拉能力,两者协同可有效控制基坑变形。本文通过理论分析与工程实践,探讨其协同作用机理,揭示土钉墙与锚杆在受力过程中的相互影响,为深基坑支护设计提供参考,推动基坑工程的优化发展。

Abstract

In deep foundation pit support projects, the synergistic action of soil nailing walls and prestressed anchor rods is key to ensuring pit stability. Soil nailing walls, through densely arranged soil nails, form a composite with the soil, enhancing the soil's shear strength, while prestressed anchor rods provide additional tensile strength through anchoring force. The synergy between the two can effectively control the deformation of the foundation pit. This paper discusses the mechanism of their synergistic action through theoretical analysis and engineering practice, revealing the mutual influence between soil nailing walls and anchor rods during the stress process. This provides a reference for the design of deep foundation pit supports and promotes the optimization of pit engineering.

Key words: Deep foundation pit support; Soil nailing walls; Prestressed anchor rods; Synergistic action; Engineering practice
