摘　　要：文中以某市区深基坑工程A-B-C区段为研究对象,论述了"强锚弱桩"与"强桩弱锚"方案相结合,可以更好的调整锚索结构的空间位置,有效避开锚索施工对周边管线的不利影响。在相近的支护效果下,对比分析了"强锚弱桩"和"强桩弱锚"每延米混凝土的不同用量,总结了"强锚弱桩"方案对桩身受力均匀性和支护成本经济性的有利影响。In this paper,A-B-C section of a deep foundation pit in an urban area is taken as the research object,Discusses the combination of strong pile weak anchor or strong anchor weak pile scheme,which can well adjust the space position of anchor cable structure and effectively solve the adverse effects of excavation on surrounding pipelines;compares and analyses the different effects of"strong anchor weak pile"and"strong pile weak anchor"on the amount of concrete per meter under similar support effect;summarizes the influence of"strong anchor weak pile"scheme on the force uniformity of pile body and support formation and beneficial impact of this economy.

关 键 词：基坑工程 强锚弱桩 强桩弱锚 支护方案 支护成本
