摘要
分析了珠海大道某人行地道的概况及工程地质条件,综合考虑基坑位置现状、地质情况、开挖深度等因素,采用坡顶卸载、四周钢板桩支护及坑内搅拌桩加固的基坑支护方案。施工结果表明,该基坑支护方案达到了设计要求,既满足了工期和造价的要求,又保证了工程质量和施工安全,从而为类似深基坑支护积累了宝贵经验。
This paper analysed the general situation and the engineering geological conditions of Zhuhai avenue pedestrian subway, considered the factors such as location situation of pit, geological conditions and excavation depth, used the pit supporting scheme of unloading on slope top, steel sheet pile enclosure and cement mixing pile inside excavation. The construction results showed that this pit supporting scheme meets the design requirements, which not only meets the demands of the working time and cost, but also ensure the engineering quality and construction safety. So it might accumulate valuable experience for the similar pit supporting.
