The highway from Xichang to Panzhihua is an important economic arterial road run-through Sichuan from south to north. Approximate one hundred of the highway go on Xigeda strata. Xigeda strata is the stillwater sediment of astatic lake facies at early stage of Quaternary Period. Because of soft lithology, low intensity and very bad stability the strata is well-known in China.
