摘要

摘要: 在岩质超深基坑中，预应力锚杆柔性支护法具有非常明显的优势，该方法造价低，工期短，施工简便，安全性好，具有较好的经济效益和社会效益。以远洋大厦超深基坑工程为背景，详细介绍了一套预应力锚杆柔性支护法设计方案，该方案的成功应用为岩质地层的超基坑支护工程提供了很好的借鉴作用。

Abstract: The tlexible retaining method with prestressed anchors for ultra-deep excavations in from rocky soil has obvious advantages: low cost, quickness, convenient in construction, great safety performance and good economic and social benefits. A detailed design for the flexible retaining method with prestressed anchors in the ultra-deep excavation of Yuanyang is introduced. The successful application of the design method provides guidance for the supports of ultra-deep excavations in rocky soil.
