摘要
齐鲁石化公司热电厂卸煤设施基坑距运行铁路很近,局部深达20m,上部土层较差而底部土层较好,经多方案比较,基于安全、经济、合理的原则,决定采用复合土钉边坡支护方案,该方案利用了复合土钉墙的超前支护作用,监测结果表明有较好的安全性和经济性。
In Thermal Power Plant under Qilu Petrochemical Company, foundation pit of coal discharging facilities is close to the railway and local depth of the foundation pit is as deep as 20 m. In the foundation pit, soil on upper layer is better than that on lower layer. After comparison among different schemes on safe, economical and rational principles, pre-supported effect of compound soil-nailing side slope supporting scheme is adopted, and monitoring results show that this construction method has high safety and economical efficiency.
