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。 For deep foundation pit support, when row piles are used as the supporting body, a ring beam is set according to the shape of the excavation foundation pit and the surrounding environment, and the crown beam and the ring beam are connected through the support and the anchor. Constitute a ring beam anchor system. The system is novel in concept, with simple process, safe and reliable, easy earth excavation, no sinking around the pit surface, and saving cost. This paper introduces two engineering examples using this system and proposes an approximate calculation method for the ring beam.
