| 摘 要： | 喷锚网支护技术在砂卵石基坑工程中的应用日益广泛 ,但是其理论研究却远远滞后于工程实践。本文结合对砂卵石基坑支护工程中应用喷锚网支护技术的介绍 ,通过现场锚杆拉拔试验、锚杆应力应变的测试以及观测基坑壁变形三项现场试验的研究 ,提出对目前砂卵石基坑喷锚网支护设计方法和施工工艺的改进意见和建议。

| Abstract: | The use of bracing technique with jet anchor in sandy gravel excavation is increasingly widespread but theoretical research lags far behind practice.Improvement and suggestion for the current design and construction of bracing by jet anchor in sandy gravel excavation are proposed herein in association with the introduction of the said technique through many field tests and monitorings. |
