立井施工中钢丝绳悬吊排水管路系统的受力计算

Analysis of the Bearing Capacity of Wirecable Hanging Drainage Systems in the Vertical Shaft Construction

本文建立了立井施工中钢丝绳悬吊排水管路系统的受力模型并且着重研究了水锤力对钢丝绳受力的影响。大量计算表明,水锤力对钢丝绳的顶部影响最大,其值为水锤力的50%,对诸卡具间的钢丝绳部分影响很小,一般小于1%,而且卡具间诸段钢丝绳受力几乎相等。

In this paper we develop a bearing capacity model for the wirecable hanging drainage system in the vertical shaft construction,and put the emphasis on the study of the influence of the water-hammer pressure (WH-P)upon the wire cable.A lot of calculations show that the influence on the top part of the wire cable exerted by the water-hammer pressure is the greatest,the top part of the wire cable bearing 50% of WHP,and that the influence upon the wire cable between the fixtures is smaller,usually less than 1%,ahd the bearing capacity is almost equal.
