Design method of pile-anchor-support combined supporting structure
The invention discloses a method for determining anchor rod arrangement and anchor rod length in a pile-anchor-support combined supporting system. The method comprises the following steps that 1, soil physical and mechanical parameters of a foundation pit of the pile-anchor-support combined supporting system and the excavation depth of each position are determined; step 2, selecting a section enclosure type of each area according to the characteristics of the foundation pit; step 3, section enclosure design; step 4, determining calculation parameters of the graphic design; 5, calculating a plane horizontal deformation curve of the enclosure structure; and 6, determining the arrangement length of the anchor rod. According to the method for determining the anchor rod arrangement and the anchor rod length in the pile-anchor-support combined supporting system, the pile-anchor-support combined supporting structure can be optimally designed, it can be ensured that deformation of all enclosure profiles meets the stability requirement of a foundation pit, the reasonable length of the anchor rod can be controlled, and the stability of the foundation pit is improved. And the stability of the foundation pit is prevented from being reduced due to overlong arrangement length of the anchor rod.
本发明公开一种桩锚撑联合支护体系中锚杆布置以及锚杆长度的确定方法，包括以下步骤：步骤1.确定桩锚撑联合支护体系基坑的土体物理力学参数及各位置开挖深度；步骤2.根据基坑特点选择各区域的剖面围护型式；步骤3.剖面围护设计；步骤4.确定平面设计的各计算参数；步骤5.计算围护结构平面水平变形曲线；步骤6.确定锚杆布置长度。本发明提供的桩锚撑联合支护体系中锚杆布置以及锚杆长度的确定方法，能够对桩锚撑组合支护结构进行优化设计，不仅可确保各围护剖面变形满足基坑稳定要求，还可以控制锚杆在合理长度，避免因锚杆布置长度过长导致基坑稳定性下降。
