回填砂抗剪强度参数试验研究

LABORATORY INVESTIGATION OF STRENGTH PARAMETER OF BACKFILLED SAND

结合交通部《港口工程结构设计统一标准》的制定,在对重力式码头墙后填料情况调查、室内填筑试验和现场随机取样控制密实度剪切试验的基础上,对龙口、秦皇岛砂的抗剪强度参数φ进行了统计分析,讨论了影响φ的诸因素,评介了回填情况下抗剪强度参数φ的取值范围。

In this paper, the distributions of the shear strength parameter φ of sand in Qinhuangdao and Longkou are obtained through statistics. The factors which may influence φ values are discussed. A range of the shear strength parameter φ value for the backfilled sands is also evaluated. The data used are collected from in-situ investigations, laboratory embankment tests and density-controlled direct shear tests on random sampling sands.
