The Gadora village landslide zone situated along National Highway 58 has become very active in recent years. The landslide zone is causing a lot of damage to property along the highway and endangering the lives of people living uphill and downhill of the slopes. In the present study, a combined geological, geophysical and geotechnical investigation has been carried out to establish the subsurface layering system of the landslide. Undisturbed and disturbed samples were collected along the depth of the boreholes to determine the engineering properties of different layers. The subsurface layering and drainage patterns of the slope were inferred from electrical resistivity tomography conducted at different stretches of the slope. The present paper describes the layering system along with the engineering and physical properties obtained from the integrated geo‐investigation. The established near‐surface geometric, hydrological and material model enabled the stability study of the slope.

印度Garhwal喜马拉雅山NH 58沿Gadora周围滑坡带的地质综合评估

近年来，位于58号国道沿线的Gadora村滑坡带非常活跃。滑坡带给公路沿线的财产造成了很大的破坏，并危及了在山坡上和下坡生活的人们的生命。在本研究中，已经进行了地质，地球物理和岩土工程的综合研究，以建立滑坡的地下分层系统。沿井眼深度收集不受干扰和受干扰的样品，以确定不同层的工程特性。斜坡的地下分层和排水模式是根据在斜坡的不同伸展方向上进行的电阻层析成像得出的。本文介绍了分层系统，以及从综合地理调查中获得的工程和物理属性。建立的近地表几何，水文和材料模型使斜坡的稳定性得以研究。
