摘要
通过对普通拉力型锚杆与压力分散型锚杆优缺点的比较及现场试验,指出压力分散型锚杆具有承载力高、经济性能优、适应强等特点,同时提出影响压力分散型锚杆承载力的因素及控制方法,对压力分散型锚杆在实际基坑支护工程中的应用具有一定的指导意义。
Through comparing the advantages with disadvantages between normal tension anchor and compression-dispersive anchor and test in project site, it can be seen that compression-dispersive anchor is of much more significant characteristics including higher bearing capacity and good economy and better adaptability. At the same time, the reasons impacting on the bearing capacity of compression-dispersive anchor and how to control them also be pointed out, which provides a guidance to the practice of compression-dispersive anchor in excavation supporting engineering.
