摘要
通过龙潭隧道右线洞口50m浅埋、偏压段施工的工程实例,简要介绍隧道偏压平衡法处理方法及施工技术;通过理论计算,确定回填厚度,平衡偏压力;为安全进洞采用水泥浆注浆固结回填料,加快施工速度,降低施工成本,取得预期效果。
Taking the construction of bias of the shallow cave at the 50meters of Longtan tunnel in the right for example, the article mainly introduces the treating method of bias-balancing and the construction technology. Through theoretical calculation, the backfilling thickness can be defined and the bias pressure can be balanced. In order to keep the cave-entering safe, the grout filling should be used to concrete the backfilling materials; the construction speed should be quicker and the construction cost should be lower. Then, the expected effects can be achieved.
