摘要
基于弹性力学理论,运用等效应力法、量纲分析法等,结合Saint-Venant原理和叠加原理,通过直角坐标系与极坐标系的转换,导出了重力坝坝体内部应力的计算表达式,可以较为精确地给出在任意水位时重力坝坝体内部任意一点的应力值。该法为重力坝的应力计算提供了新的思路,也可为重力坝坝体强度的综合评定提供研究依据。
Based on the elasticity theory, combined with Saint - Venant principle and the superposition princi- dinate system and Polar coordinate system. The method not only offers a new mode for calculating the stress of grav- ity dam, but also presents research bases for synthetically evaluating the strength of gravity dam.
