摘要
筒式基础结构在贯入过程中和正常工作状态下都会与周边软土地基产生相对滑动,软土的抗剪强度或混凝土与软土间的摩擦系数是确定筒体下沉贯入力和筒式结构在工作状态下承载力的重要参数。通过对采自连云港港徐圩港区现场的2种淤泥土样与混凝土板间的滑动试验发现,在混凝土板滑动摩擦力的作用下淤泥内部发生剪切破坏,测得该状态下淤泥的抗剪强度,可为相关工程设计提供依据。
The cylindrical foundation structure slides correspondingly against soft soil foundation no matter whether it is in the process of penetration or normal working state. As an important parameter, the shear strength of soft soil or the friction coefficient between concrete structure and soft soil determines the penetrating power while the cylindrical structure is going down and the bearing capacity while it is in working state. The sliding experiment between the concrete slab and two kinds of silt sampled from Xuwei Port Area of Lianyungang Port is conducted. The trial result indicates that silt sampled is sheared broken by itself, the measured shear strength in this condition will provide references for related project design.
