ANALYSIS ON THE INFLUENCE OF SWELLING PROPERTY OF RED MUDSTONE ON ENGINEERING IN NANNING AREA
This paper analyzes the expansibility of red-layer mudstone in Nanning area under alternating dry and wet conditions,and compares and analyzes the expansibility changes of mudstone layer before and after weathering.Relying on Nanning rail transit project,weakly weathered red-layer mudstone and regolith in different ages such as Paleogene and Cretaceous are selected as research objects.This paper studies the influence of swelling property of red layer mudstone and weathering on the stability and safety of foundation pit,slope and road engineering in Nanning area.
