摘要

结合某基坑工程的设计实践

对在基坑开挖深度内有土层和岩层、且岩层内存在软弱夹层的二元地质条件下采用内支撑和复合土钉墙组合形式支护时存在的问题进行了详细分析

主要包括土压力的计算模式、钢管桩下局部地基承载力的验算、刚-揉性组合支护型式的交接处刚度协调、内撑立柱的约束状态对内支撑稳定性的影响等问题

通过对这些问题的分析

得到在设计类似基坑支护形式时需要注意的问题

并提出解决问题的措施

为同类工程提供参考。

Abstract

Combined with the design practice in foundation excavation engineering

the problems for combined supporting from inner supports and composite soil nailing wall under binary geological conditions

including soil layers and rock stratum with weak intercalation in range of excavation depth

are analyzed.These problems mainly include the following: calculation model of earthen pressure

the local bearing capacity of foundations below steel pipe piles

stiffness coordination at the junction of rigid and flexible supports

internal bracing stability influencd by restrained condition of upright post

etc.Problems of concern for design of similar foundation pit supports are pointed out

and measures for solving these problems are proposed.All these can provide references for similar projects.
