文档介绍：浅析两种锚杆施工技术的不同施工方案中英文
Analyses two kinds of different construction schemes of anchor rod construction technology
近年来,水利水电工程中一些大规模的地下洞室工程越来越多。从跨度与边墙角度来说,地下厂房的规模同以前相比都有了很大的增长。在开挖过程中,对岩体的稳定性会造成一定影响。其中原因有很多,主要由于岩体的应力分布发生了不均匀变化。由于应力分布的重组,产生了塑性区或拉力区。再加上先天地理条件的影响。进而就会导致围岩的松动甚至事故。因此,为了保持岩体稳定,防止工程中出现不必要的损失,需要做好支护工作。
In recent years, some large scale underground caverns in water conservancy and hydropower project engineering more and more. From span and side wall Angle, the size of the underground powerhouse with there were a lot of growth than ever before. In the process of excavation, can cause certain influence to the stability of the rock mass. In which there are many reasons, mainly due to the uneven changes have taken place in the stress distribution of rock mass. Due to the restructuring of the stress distribution, plastic zone and tensile zone. Coupled with the natural geographical conditions. Which will lead to the surrounding rock looseness or even accidents. Therefore, in order to keep the stability of ro
ck mass, to prevent the occurrence of unnecessary loss in the project, the need to do a good job of supporting.
本文以某水电站地下厂房为例,主要对普通预应力锚杆施工技术与水泥药卷预应力锚杆施工技术进行了对比,通过探讨分析,最终选择了后者作为本工程的施工方案。
Taking a hydropower station underground factory building as an example, the main mon prestressed construction technology of anchor and cement cartridge prestressed anchor rod constructi
