洛阳理工学院毕业设计（论文） PAGE  PAGE 71  PAGE 71 六冶佳苑G3楼地基处理及基坑支护设计 摘要 本设计为洛阳市六冶佳苑住宅小区，根据地质情况、周围环境，考虑到社会经济效益综合众多支护技术的特点，同时参考当地的建筑经验和施工现场的具体情况，完成了该住宅基坑围护的方案论证和设计。其中地基处理采用刚柔性桩复合地基，基坑支护分别采用桩锚支护和土钉墙支护两种方案，运用了理论计算、土力学、结构力学、钢筋混凝土、基坑支护等专业技术，对钻孔灌注桩的结构内力、结构构造、支撑锚杆进行计算设计。 本论文主要通过土钉墙以及钻孔灌注桩与锚杆支护结构在某基坑的应用，介绍了基坑围护结构——桩墙的设计，并进行了围护桩墙的内力计算、结构计算；支撑结构——锚杆的设计，进行了锚杆的内力计算、结构计算,验算包括桩锚系统的抗隆起验算、抗倾覆验算、深层剪切滑移验算、整体稳定性验算。结构设计合理，节省造价，施工方便，工期合理。 关键词：深基坑工程；地基处理；灰土桩；CFG桩；基坑支护；土钉墙，钻孔灌注桩；锚杆；稳定性验算； Found Treatment and Excavation Design Process of Six metallurgical Jiayuan G3 building ABSTRACT The design is for the rule of Luoyang six Jiayuan residential area. According to the geological conditions and the surrounding environment, we take into account the socio-economic benefits of supporting technology integrated many features,and refer to local building experience and the specific circumstances of the construction site,and finally complete the residential base pit envelope demonstration program and design. Found treatment is using rigid flexible piles composite foundation,and excavation were used to pile anchor and soil nailing ,in the design we have used heoretical calculations, soil mechanics,structural mechanics, reinforced concrete, excavation and other professional technology,finally design bored forces on the structure, structures, supporting bolt. This thesis is mainly about applications of soil nailing and bolting bored with the structure of a pit,and it describes the foundation pit construction- pile wall design, and carrys out retaining pile wall force calculation, structural calculations; support structure - soil anchor design, carrys out bolt force calculation, structural calculations; support structure - soil anchor design, carrys out bolt force calculation, structural calculations;Checking is including pile heave anchor system checking, checking against overturning, deep shear sliding checking, checking overall stability.Structure design is reasonable,cost is saving, construction is c
