Abstract

The geometric shape of the slide surface and the topography of before and after the failure are the essential factors for analysis of a landslide and for design of remedial works. Since determination of the slide surface profile is difficult and costly using traditional methods and often the pre-slide topography is not accessible, this paper is going to present two techniques to determine these factors. The presented technique to locate 3dimensional geometric shape of the slide surface is based upon determining slide surface in 2dimensional vertical sections. The outcrop and other signs of slide surface are implemented factors for this method. The next method utilizes post-slide topographic situation of the area to determine the pre-slide topography. This method obtains some equations in order to achieve the pre-slide situation of the points which located on the sliding mass by a statistical process. These methods are tested by a case study about Maskun landslide. The results indicate the applicability of the proposed methods to obtain the vital factors for back analysis and abandon a costly and difficult process.

Locating Slide Surface and Pre-Slide Topography Using Site Investigation Data, Case Study: Maskun Landslide
