摘    要:本文提出一种解析的方法,将竖井结构看作一端简支,一端轴向弹性支承的有限长中厚园柱壳,求得其在冲击波作用下的动力响应,着重考察了地层基床系数的影响。算例表明,当主要关心Nzx值时,竖井底部简化处理成刚性固结,没有造成很大偏差。

关 键 词:竖井    响应  冲击波

Abstract:In this paper, an analytical method is presented to the dynamic response analysis of the shaft structure subjected to shock waves. The shaft structure is modeled as a finite, moderate-thick circular shell with one end simply supported and another end sup-potted by axid springs. Attention is pald to the influence of ground resistance coefficient. Numerical examples show that if we are mainly concerned for the value Nxx it would only make small deviation for the shaft structure modeled as rigidly clamped at the bottom. Thus calculation would be simplified.
Keywords:stiafts. shell   response   shock waves.
