水工隧洞温度应力计算问题,是大家所关心的问题。由于考虑温度应力时牵涉所及的因素太多,目前尚缺乏完善的计算方法。本文介绍的是笔者从需要出发,初步总结出一套计算方法,以供实际应用。本文讨论的湿度应力,是指隧洞通水后,低温水使隧洞周围的混凝土衬砌及岩石的温度逐渐降低,结 Hydraulic tunnel temperature stress calculation, is everyone’s concern. Due to the many factors involved in considering temperature stress, there is a lack of a sound calculation method. This article describes the author from the need to proceed, initially summed up a set of calculation methods for practical application. The humidity stress discussed in this article refers to the temperature of the concrete lining and rock surrounding the tunnel gradually decreasing after low temperature water is passed through by the tunnel
