绍兴山水人家3号地块基坑支护设计
摘 要
本设计为住宅楼的基坑支护设计。本设计是根据行业现行建筑基坑支护技术规程,在给定地质勘察报告的条件下，进行基坑支护设计，主要目的是掌握基坑支护的设计方法。本设计采用了钻孔灌注桩加锚杆的基坑支护结构。在土压力计算过程中，运用了朗肯土压力理论；在内力计算过程中，运用了等值梁法；在配筋计算过程中，参照了混泥土结构设计规范;在降水处理设计时参照了建筑基坑支护技术规程；计算过程中除了以国家现行建筑基坑工程技术规程为依据外,还大量的把实际经验运用其中,加强理论与实践的结合。此次设计的主要指导原则是如何保证基坑的安全可靠、方便施工，并达到经济的效果。通过这篇设计说明书，直观的说明了基坑支护设计所需的各种参数。工程技术人员在进行基坑支护设计时可参照本文的设计方法。
