本文选用西南交通大学自编的“SWR2”程序,对渔子溪一、二级和南丫河三级三个水电站引水隧洞的五个典型塌方断面,进行了“反演计算”,各断面计算的破坏区范围线与实际的塌方形态十分相似;同时还确定了各典型塌方断面的破坏突破区和突破点。本文是用“反演计算法”对水工隧洞塌方机理分析的初次尝试。
This paper selects “SWR2” program compiled by Southwest Jiaotong University to conduct “inversion calculation” of five typical landslides of diversion tunnels of three hydropower stations of Yuzixi Grade I, Grade II and Grade III of Nanyang River. Each section is calculated Of the destruction of the scope of the line with the actual collapse of the form is very similar to; also determine the destruction of various typical sections of the breakthrough area and breakthrough point. This paper is the first attempt to analyze the mechanism of collapse in hydraulic tunnels by using “inversion calculation method”.
