深基坑支护工程中经常会用到锚杆支护,但在高水位松散砂层中施工预应力锚杆的难度很大。以福州某基坑施工为例,通过对桩间涌水、涌砂现象的原因分析,探讨了在高水位砂层中采用锚杆支护的方法,提出了“孔口堵水后注浆”的施工工艺,为今后进行类似工程提供借鉴与实践依据。 Anchor support is often used in deep foundation pit support projects. However, it is very difficult to construct prestressed anchor in loose sand layers with high water level. Taking the construction of a foundation pit in Fuzhou as an example, the paper analyzes the reason of gushing water and gushing sand between piles, and discusses the method of using bolt support in high water level sand bed. "Of the construction process for future similar projects provide reference and practice basis.
