摘要
华丽高速公路第20合同段土石方开挖过程中,通过分析地质参数和水文情况制订了开挖的边坡坡度和分台高度,采取“少开挖,强防护”的施工措施,合理设置便道便桥;对填方路基制订了处理方案,提高了支护系统的施工质量。
During excavation of the 20th contracted segment of Huaping-Lijiang expressway,the geological parameters and hydrological conditions were analyzed to determine the excavated grade of side slope and step height.The construction measure of less excavation and strong protection was adopted to reasonably set overhead passage.Treatment method was established for backfilled road foundation to improve construction quality of the support system.
