强风化花岗岩弹塑性本构模型研究(Ⅰ):理论模型及参数反演
Study of elastoplastic constitutive model of strongly weathered granite Part Ⅰ : Theoretical model and parameter inversion
摘要
Abstract
Xiamen subsea tunnel is the first undersea road tunnel in China. The investigation, design, engineering experience will be used for reference to other subsea tunnels' construction. The encountered problems about rock mechanics and tunneling designs for subsea tunnel construction are more complicated than other road tunnels. There are many problems which the present criteria have not be covered yet; and all the questions are urgently needed to be solved. In order to study the mechanical characteristics of the host rock in weathered strata, a strain hardening elastoplastic model and cohesion evolution equation are established to describe the hydro-mechanical coupled behavior of the strongly weathered granite based on laboratory test results; and corresponding parameters have been identified by back analysis. The developed strain-hardening elastoplastic model can well describe the mechanical characteristics of strongly weathered granite. The method suggested in the paper is worthy to be widely used.关键词
