三峡工程茅坪溪防护土石坝施工期安全监测

Safety monitoring during construction period at TGP's Maopingxi Protective Dam

介绍了三峡工程茅坪溪防护坝的安全监测布置和沥青混凝土心墙在施工期的温度变化 ,如墙体突破软化点的深度。通过资料分析并及时调整施工程序 ,控制了因两侧过渡料碾压不均衡产生的墙底接触面错动。

This paper introduces the arrangement of safety monitoring of TGP's Maopingxi Protective Dam and the duration of temperature inside the asphalt concrete core wall at construction period (such as the depth where the temperature of the core wall exceeding its softening point).By analysing the monitoring data and adjusting the construction procedure in time,the relative displacement at contact surface of the wall footing caused by non uniform roller compaction of transient materials on both sides of core wall has been controlled.
