Abstract

Abstract

Based on the 1:50000 geological survey of Songpan map and Zhangla map, through the field geological survey, geological dating, geography space analysis, laboratory test and in-situ large scale direct shear test, the development and distribution characteristics and engineering geomechanical properties of the Songpan loess are studied in this article. The Songpan loess has the following features:(1) The Songpan loess is an eolian deposit and the changes of local terrain affect the accumulation of the Songpan loess by controlling the movement of the air near the ground. So the distribution of the Songpan loess is closely related to the topography and geomorphology of the study area.(2) The Songpan loess contains more than 80% silt and mostly with gravels, and the material composition of gravels mainly are sandy slate, carbonaceous slate and quartz.(3) The Songpan loess in the study area is mainly distributed within the scope of elevation between 2712~2712 m, mostly in the south slope of the mountain, within the broad fault basin. It has a large and extensive continuous distribution, while in the deep canyon area with a patchy distribution. (4) The Songpan loess has a distinct structure, and its mechanical properties are influenced by material composition, moisture content and natural structure plane, with an intermediate to high collapsibility. The loess characteristics of structure, water sensitivity and collapsibility are the main factors in the development of geological disasters in the strata and the construction of the future major projects in the research area will be influenced by the undesirable engineering geological characteristics and geological disasters of the Songpan loess.
