摘要： 对于稳定岩体条件下土岩双元基坑,吊脚桩虽已广泛应用,但其工作机理尚未形成共识,解析计算方法也显不足。针对这一问题,基于圆弧、圆弧-平面、切面、滑切4种破坏模式及其随土体深度的变化规律,深入分析不同破坏模式的力学机制,推导出基于静力平衡方程的嵌岩深度计算公式;确定考虑土、岩分别破坏和考虑不同路径组合破坏模式的整体破坏系数S的定量判据。结合青岛、济南的工程案例,提出破坏模式判定、支护选型、嵌岩深度计算、整体稳定验算设计方法,进行土岩双元基坑全回收吊脚桩应用,并采用全回收支护结构优化,提升土岩双元基坑高质量发展水平。

关键词: 土岩双元基坑, 吊脚桩, 破坏模式判据, 计算理论, 设计方法

Abstract: Aiming at the problems of the wide application of foot-hanging piles in soil-rock dualistic foundation pits with stable rock masses, yet the lack of consensus on their working mechanism and insufficient analytical calculation methods, this paper conducted an in-depth analysis of the mechanical mechanisms of four failure modes(circular arc, circular arc-plane, cutting plane, and sliding-shearing)and their variation laws with soil depth, derived a calculation formula for rock-embedded depth based on static equilibrium equations, and determined the quantitative criterion of the overall failure coefficient S considering the respective failures of soil and rock as well as the combined failure modes with different paths. Combined with engineering cases in Qingdao and Jinan, a design method was proposed, which included failure mode judgment, support type selection, rock-embedded depth calculation, and overall stability checking. The fully recoverable foot-hanging piles were applied in soil-rock dualistic foundation pits, and the fully recoverable support structure was optimized to promote the high-quality development of soil-rock dualistic foundation pits.

Key words: soil-rock dualistic foundation pit, foot-hanging pile, failure mode criterion, calculation theory, design method
