摘　　要：以渝湘高速公路彭武段铁碛坝大桥工程为例,介绍了岩堆体的稳定性分析,在银盘水电站水位抬升后,对岩堆体的稳定性不利。采用综合工程措施,对岩堆体进行整治。监测显示,整治后的岩堆体处于稳定状态,确保了大桥的安全。Taking the Tieqiba Bridge project on Pengshui-Wulong Section of Chongqing-Changsha Highway as an example, the stability analysis of the rock heap was conducted, with the unfavorable conditions against the stability after the water level in Yinpanshui Power Station rose. Using comprehensive engineering treatment measures, the rock heap was treated. Through monitoring, it shows that the rock heap is stable and the safety of the Bridge is secured. It can be used for reference in similar engineering.
