摘要
以实际工程为例,介绍预应力管桩支护体系在连云港软土场地基坑中的应用。计算分析表明,软土层对管桩支护体系的稳定性影响很大,实践中采用增加支护桩长度,使桩身穿越淤泥层,以满足稳定性计算的要求。工程监测结果表明,预应力管桩支护体系在连云港软土场地具有良好的适用性,工程的成功经验可供类似软土基坑工程参考。
Taking a project as an example, this paper introduces the application of the prestressed pipe piles in the excavation support system of Lianyungang City. According to the calculation and theoretical analysis, it is reasonable to increase the length of pipe piles for stability calculation. Monitoring results show that prestressed pipe piles are applicable for the local excavation support system. Such a study can provide references for similar soft-soil projects.
