锚杆护桩支护是目前高层建筑深基础基坑支护施工中常用的方法之一,目前这一领域尚无十分成熟的理论。近几年我公司在平顶山市施工了三个工程,取得了一点经验。平顶山市保险大厦高十几层,基坑深8.0m,基坑与相邻建筑物基础净距4.0m,我们采用沉管灌注档土桩一层土层锚杆拉结。平顶山市金三角商场高九层,基坑深3.5m,北面与相邻建筑物的基础净距3.0m,东面与相邻建筑物净距1.4m。北面采用直径1000mm悬壁 Anchored pile protection is one of the commonly used methods in the deep foundation pit support construction of high-rise buildings. There is no mature theory in this field. In recent years, our company has built three projects in Pingdingshan and gained some experience. Pingdingshan City Insurance Building more than a dozen layers, the pit depth of 8.0m, the foundation pit and the adjacent building base net distance of 4.0m, we use immersed pipe piled soil pile anchor bolt tie. Pingdingshan City Golden Triangle Shopping Center is a nine-storey building with a deep pit of 3.5m, a net distance of 3.0m from the north and neighboring buildings, and a clear distance of 1.4m from the neighboring buildings to the east. The north uses a diameter of 1000mm
