摘　　要：对于较深的基坑支护，当采用排桩作支护主体时，根据所开挖基坑平面形状与周围环境，设置一道环梁，通过撑、锚将桩顶冠梁与环梁联接，构成环梁撑锚系统。该系统构思新颖，具有工艺简单，安全可靠，土方开挖方便，基坑周围表面无沉陷，节省造价等特点。本文介绍了应用该系统的两个工程实例，并提出了环梁近似计算方法。When the concrete pile walls are adopted for deep excavation,according as the plane shape of pit and surroundings around excavation,a ring beam in combination with beams at the top of piles,tie rods and compression bars can make up a support system at the top of pile walls This system is of novel conception,and has advantages of simple construction,safety,convenient excavation of earth,no surface subsidence around excavation and economization of cost In the paper its use in two engineering examples is introduced and the approximate calculation method for the ring beam is given
