二向不等围压和线性内压下椭圆形水工洞室的应力计算

Stress Calculation of Elliptic Hydraulic Cavern under the Joint Actions of Two-dimensional Unequal Confining Pressure and Linear Internal Pressure

应用复变函数保角变换方法和弹性力学理论,推导了椭圆形水工洞室在线性内压和二向不等围压共同作用下应力的计算公式,并给出椭圆形水工洞室的应力解析公式。其推导方法也适用类似工程问题的求解。

The formula of elliptic hydraulic cavern under the joint actions of linear internal pressure and two-dimensional unequal confining pressure is deduced using complex function conformal transformation method and elasticity theory,and the stress analytical formula of elliptic hydraulic cavern is given in this paper.This method can be also applied for solving the similar engineering problems.
