Development of advanced measurement techniques and numerical analysis for surface failure of slopes during torrential rainfall (guerrilla-like rainfall)

在本研究中，开发了更先进的测量技术，用于准确估计暴雨（所谓的游击式降雨）期间斜坡的降雨剖面和水质量平衡，以研究降雨入渗和降雨引起的地表破坏机制。开发了先进的数值模拟工具，对暴雨条件下的边坡稳定性进行了评价，并模拟了边坡破坏/崩塌过程。将新开发的数值模拟工具应用于边坡的实际地表破坏，并对其有效性进行了验证。

In this study, more advanced measurement technique for accurate estimation of rainfall profiles and water mass balance in slopes during torrentialrainfall (so-called guerrilla-like rainfall) was developed to investigate the mechanism of rainfall infiltration and rainfall-induced surface failure. The advanced numerical simulation tools were also developed to evaluate the slope stability and simulate the slope failure/collapse processes during torrential rainfall. The newly developed numerical simulation tools were applied to the real surface failure in the slope and their validity was investigated.
