在基坑工程中,桩-撑和桩-锚是两种为应用非常广泛的支挡式支护形式。桩-撑-锚组合支护技术是结合了桩-撑和桩-锚支护结构的优点,扬长避短,达到“刚柔并济”的效果。它即可有效控制基坑周边变形,又为土方和地下结构施工创造方便条件。本文在对比几种支护形式的基础上,结合典型基坑工程案例,从设计、施工及监测结果等方面进行了较为详细的介绍和分析。
In the foundation pit engineering, pile-support and pile-anchor are two kinds of support type which is widely used. The pile-support-anchor combination support technology combines the advantages of pile-support and pile-anchor support structure, and achieves the effect of “rigid and flexible”. It can effectively control the deformation around the pit, but also for the earthwork and underground structures to create convenient conditions. Based on the comparison of several types of support forms, this paper presents a detailed introduction and analysis from the aspects of design, construction and monitoring results in combination with the typical cases of foundation pit engineering.
