摘要
众所周知,扬压力是作用在大坝上的重要荷载之一,如何降低扬压力则主要取决于坝基混凝土与基岩接触面胶结情况。本文从新安江二、三坝段基础补强造孔时采集的岩心,探讨接触的优劣及成因分析,反馈于实践,供设计,施工和运行维护参考。
It is well known that the uplift pressure is one of the important loads acting on a dam, and its reduction mainly depends on the cohesion between the dam concrcte and the base rock. Based on the rock cores sampled from the drilling which was condueted to strengthen the foundation of the Ⅱ and Ⅲ dam sections of the Xinanjiang Dam, this pa per discusses the factors affecting the contact quality. The results obtaincd can be used as reference in design, constraction, operation and maintcnance.
