摘要
竖井井颈是接近地表的一段井筒,大多位于表土段与基岩风化层之中。结合表土层地质条件与所受荷载特点,从侧向和竖向两个受力方向,对印度某副井不设壁座情况下井颈的厚度、配筋及井颈变直径尺寸进行了计算分析,可为同类工程井颈设计计算提供参考。
The mine shaft collar is a part of the shaft near the surface of the earth, most of which are located in topsoil and bedrock differentiation layer. Combined with the geological conditions of the topsoil and the characteristics of the load, the paper analyzes and calculates the thickness, reinforcement and variable diameter of the shaft collar of an Indian auxiliary shaft without wall support from the lateral and vertical stress directions, which can provide reference for the design and calculation of the shaft neck of similar projects.
