The method of anchor calculation of dangerous rock mass and its application in the three gorges reservoir 三峡库区危岩体锚固计算方法及应用
Abstract : the traditional method of anchor pile on the deep foundation pit bracing in the gravel stratum with high hardness , poor drilling and easy slump is complicated owing to difficult construction , low efficiency and high cost 文摘:卵砾石地层硬度大,可钻性差,易坍塌,这种地层的深基坑支护若采用传统的锚杆桩,施工难度大,工效低,工程造价高。
So far , though the anchor bolts are widely used in tunnel , slope and deep excavation engineering for their convenience in construction and good effect , the theory on the calculating and design method of anchor bolts studies are not so perfect and remain to be developed 在隧道、边坡、深基坑等各类岩土工程中,锚杆因施工简单且效果良好得到了相当广泛的应用,但其相应的计算及设计理论并不十分成熟。
The paper discusses methods of anchored bar supporting in soil with confined aquifer and puts forward creatively constructing process of blocking up first and then grouting for a case of excavation , which can be refered by similar engineering located in the area near seas or rivers 以深圳某商住楼基坑施工为例,探讨了在承压水土层中采用锚杆支护的方法,创造性地提出了“先堵水后注浆”的施工工艺,可供沿海、沿江地区的类似工程借鉴。
Application of the new type wall in engineering practice proves the feasibility and advantages . in the end , comparison between measured data from quite a few engineering examples and calculated theoretical results shows that , the design methods of anchored bar retaining walls and block retaining walls presented in this paper are reliable , which also have a better bearing behavior and good social and economic benefits 最后通过计算实例以及现场实测结果的对比分析,证明了锚杆挡土墙和砌块式挡土墙的设计计算方法是安全可靠的,同时证明了锚杆挡土墙和砌块式挡土墙优越的受力性能以及其良好的社会经济效益。
