| 中文摘要: |
| 本文以昆明软土地区某复杂深支护工程项目为实例,在系统收集、深入分析拟建场地工程地质及水文地质特征的基础上,通过现场踏勘,综合分析、理论计算、现场试验、监测等手段,紧密结合基坑开挖范围及深度、周边环境情况与基坑关系等要素,就内支撑与桩锚支护形式进行对比分析与选型,并对各类不同工艺锚索拉力进行试验测试,最终采用一种新型扩体锚索作为施工工艺,有效保障了毗邻构筑物的安全与稳定,为同类工程提供了理论依据与实践思路。 |
| 英文摘要: |
| Based on the systematic collection and in-depth analysis of the engineering geological and hydrogeological characteristics of the proposed site, this paper takes a complex deep support project in the soft soil area of Kunming as an example. By means of on-site survey, comprehensive analysis, theoretical calculation, on-site test and monitoring, and in close combination with the excavation scope and depth of the foundation pit, the surrounding environment and the relationship between the foundation pit, the internal support and the pile are discussed The anchor support forms are compared, analyzed and selected, and the tension of anchor cables of different processes are tested. Finally, a new expansion anchor cable is used as the construction process, which effectively guarantees the safety and stability of adjacent structures, and provides theoretical basis and practical ideas for similar projects. |
