摘要
广西建筑科学研究院高层住宅工程基坑深约9.3m,为确保安全经济、技术可靠,采用内支撑排桩支护结构和扩大头锚杆支护结构两个方案进行技术、造价等方面的对比,并考虑施工过程的影响,结果表明扩大头锚杆支护在技术经济方面占优,被确定为实施方案。
The foundation pit of high-rise residential buildings of Guangxi Institute of Building Research and Design is about 9.3 m. In order to guarantee safe and economic construction and technical reliability, comparison on aspects of technique and cost is made between internal support row pile structure scheme and expanded anchor rod supporting structure scheme, with consideration of influences generated during construction. The comparison result shows that expanded anchor bolt has better technical and economic advantages and is determined as the final construction scheme.
