摘要
在城市基坑支护中,由于大量不能回收的传统拉力型锚杆的使用,不仅造成地下空间的污染,而且为后续工程留下严重的隐患。压力分散型锚杆很好地克服了传统拉力锚杆的缺陷,并得以回收利用。以宋家庄地铁站基坑支护中压力分散型锚杆施工为依据,表明压力分散型锚杆的应用前景。
In the foundation pit cutting of large city,the use of traditional pull anchor bar which can not be recovered,not only causes pollution of underground space,but brings serious pitfalls for future engineering.The pressure dispersive anchor bar overcomes the defects of traditional pull anchor bar and can be recovered.Taking Songjiazhuang subway foundation pit cutting for example,the application prospect of pressure dispersive anchor bar is indicated.
