摘要

摘要: “桩（墙）–撑–锚”联合支护是在“桩（墙）–撑”和“桩（墙）–锚”两种支护技术的基础上，扬长避短，研发的一种具有综合优越性的新型联合支护形式。它既可有效地控制基坑周边变形，又为土方和地下结构施工创造了方便条件。这种新型支护在3个深基坑工程（H=11～20.9 m）中应用效果良好。论文还对“桩（墙）–撑–锚”联合支护形式的变形协调问题进行了探讨，认为技术关键是加大锚杆的刚度和变形控制能力。在分析比较这种新型支护与“桩（墙）–撑”支护在基坑施工和使用三阶段变形特点后，认为在采取适当的技术措施的基础上，基坑深层总变形量达到两者相当的水平是可能的，并就提高基坑深层变形控制能力提出了5条措施。

Abstract: The combined support of pile (wall)-bracing-anchor, a new supporting type, has been developed based on pile (wall)-bracing and pile (wall)-anchor and has more advantages. It can effectively control the surrounding deformations of excavations and facilitate the excavation and construction of underground structures. The application of the new supporting type in three projects has achieved good results. Based on the studies on the deformation compatibility of the combined support of pile (wall)-bracing-anchor, increasing the stiffness and the ability to deformation control of anchors is the key technique. It’s believed that deep displacements of the new supporting type and the pile (wall)-bracing support can achieve the similar level by taking some measures through analyzing the deformation characters of these two types during three stages of foundation construction-use-bracing substitution, and five technical measures of enhancing the ability to control deep displacement are provided.
