摘要
结合基坑支护工程实例,介绍了昆明软弱泥炭质土层高压旋喷扩体锚索在深基坑支护工程中的施工工艺及锚固试验。通过不同的施工工艺试验分析,探索针对该场地软弱地质条件下的预应力锚索施工工艺,以确保预应力锚索施工达到设计要求承载力,保证预应力锚索的有效性和基坑支护结构体系的可靠性。
Based on engineering practice, this paper introduced construction technique and anchorage test of high pressure rotary jet grouting anchor cable of foundation excavation supporting in peat soil in Kunming. According to the testing analysis on different methods, this paper explored construction technique of prestressed anchor cable in soft soil which can ensure the bearing capacity of anchor cable meet the design requirement and the supports is effective and reliable.
