浅谈拱坝砌体的抗压作用应予重视

Elementary Introduction to Compressive Property of Arch Dam Masonry Envelope Calling for Due Attention

拱坝设计中的应力计算一般是以拉应力为控制条件,往往造成计算压应力偏小,未能充分发挥拱坝砌体抗压性能好的特点。作者根据多次参加地方中小拱坝设计并参考了大量资料,对上述应力控制从计算理论,基岩条件,形体布置,河谷形状和坝型选择等方面进行了探索与思考。

Tensile stress is in general taken as a control factor of stress calculation in the design of an arch dam, which often causes the compressive stress to be on low side in calculation and can not give full play to desired compressive property of an arch dam masonry envelope. Having been engaged in design of a number of arch dams in the region and having consulted a vast amount of technical information and data the author has made investigation and study of the stress control problem in terms of calculation theory, bedrock condition, structural configuration, shape of valley and selection of dam type.
