摘　　要：广州市猎德变电站基坑依据地质条件分段确定钻孔灌注桩加内支撑、钻孔灌注桩加预应力锚杆、放坡与土钉相结合等多种支护综合优化方案。由于该基坑临近珠江,地质条件较差。为确保基坑安全而布置详细基坑工程监测方案,实行信息化施工,及时解决发生的险情,并从中得到了一些有益的结论可供设计、施工和监测参考。The bored cast-in-place pile with interior support and prestressed anchor, slop and soil nail are co mbined to for m the optimized co mprehensive retaining structure. On account of bad geological conditions, the monitoring design is prepared in detail to make excavation eonstruction infor mationized, thus the potential danger is avoided by taking technical measures in ti me to guarantee the excavation safety. The displace ments and stress data are useful for the engineering, construction and monitoring.
