摘要
挡土墙在边坡治理与支挡中广泛运用,挡土墙的选型与基础处理是决定边坡工程造价的关键因素。针对某石化企业大型边坡设计方案不能满足施工进度要求这一问题,提出采用复合地基上的扩展基础新方案。对复合地基和扩展基础分别进行了设计计算,结果表明该方案可行。实施后经过检测和实际考验,表明该挡土墙的地基满足承载力要求,挡土墙满足使用要求,并取得了较好的经济效益。
Retaining wall is widely used in slope treatment and supporting structures.The selection of wall type and foundation improvement technique plays a key role in the slope project cost.A new scheme of spread base on improved composite foundation is proposed to solve the problem of dissatisfying the construction schedule requirement encountered in the large slope design scheme in a petrochemical enterprise.The design calculations for both composite foundation and spread base validate the practicability of the new scheme.Post-constructional inspection and test indicate that the bearing capacity of the retaining wall foundation meets the requirement,the retaining wall satisfies the functional needs and the engineering application gains good economic benefits.
