摘　　要：对于周边环境比较复杂的基坑,如何控制基坑侧向变形成为支护设计的重点和难点。以某桩锚支护为例,对于局部空间受限的情况,采用大角度多道锚杆的方式较好的避免了锚杆施工对临近地下结构的影响,同时控制了该位置的基坑变形,保证了基坑的安全,基坑及环境变形监测表面,该支护方式取得了良好的支护效果。For the foundation pit with complex surrounding environment,how to control the lateral deformation of foundation pit becomes the key and difficult point of support design.In this paper,a pile anchor support is taken as an example.For the limited local space,the large angle multi-channel anchor method is used to avoid the impact of anchor construction on the adjacent underground structure.At the same time,the deformation of the foundation pit is controlled to ensure the safety of the foundation pit.The foundation pit and environmental deformation monitoring surface have achieved good support effect.
