摘要
Abstract
lithological Depending weathering evaluated. Gravel Bed gravel beds Quarternary sediments are distributed in a large area at the southwest edge of Chengdu Basin. The character as a whole is a set of yellow-grey, or sallow sandy gravel bed and clay bed primarily. on the results of field investigation and part of tests about many railways, the genesis and characteristics of the gravel bed are studied, and the properties of the engineering geology are According to the genesis, it is divided into four categories : Dayi Gravel Bed ( Q1 ), Mingqi (Q2^1), Dansi Gravel Bed (Q2^2), and Ya'an Gravel Bed (Q3^1). There are weathering in in the area generally affecting the engineering properties obviously. ong the关键词
