Abstract As the large-scale development of engineering construction and extreme weather in Chian，numbers of swelling rock and soil landslide problem happened，but the related codes can't satisfy the requirement of swelling rock and soil landslide treatment. 44 engineering cases of swelling rock and soil landslide treatment are collected，firstly analyzing the success or failure reason to the three typical landslide treatment engineerings，pointing out that the reasonable determination of the sliding surface and shear strength are crucial to the swelling rock and soil landslide treatment；secondly statistical analyzing the shear strength index for swelling rock and soil of Guangxi，the foundation horizontal resistance coefficient and bonding strength within mudstone and mortar；finally putting forward the special rules of the conventional method used in swelling rock and soil landslide treatment：must setting up drainage system and should meet the codes for expansive soil；cutting and shedding load used in the permanent treatment should be careful；the designing of retaining wall should meet the codes for expansive soil，and should not be more than 3 meters height；the anchorage segment of anti-slide pile should be more than the influence depth of atmosphere，reducing softening by water to the rock and soil around pile when boring；the use of anchor supporting should be careful，and the anchorage segment should be more than the influence depth of atmosphere，hole should be dry-bored.

Key words： engineering geology swelling rock and soil landslide treatment measures
