摘要
长柱状重力取样器在地质考察中应用时,在破土阶段、起升阶段和出水阶段对缆绳的作用力是不同的;同时,在同一阶段,不同的取样管长度、形状和底质层等对缆绳拉力的影响不同,而支撑该缆绳拉力的主要设备是地质绞车。在对此类工况进行充分研究的基础上,为设计者提供地质绞车拉力取值的指导,并针对长柱状重力取样优化提出前瞻性建议。
The cable loads of the long column sample gravity corer are different during the ground breaking stage,the lifting stage and the surfacing stage.Even in the same stage,the cable loads are influenced by the length and shape of sampling pipe and the bottom properties.The main equipment to provide the pulling load is the geological winch.After sufficient studies on such conditions,the guidance for estimating the pulling load of geological winches is provided for the designers,and the suggestions for the optimization of long column sample gravity corer are proposed.
