Abstract: A three axis UU shear strength property of remolded soil of weathered sandstone splint rock with different soil moisture content and dry density was studied at greening slope of a big and a small landslide, respecitively, located in Xuelang Mountain by Binhu District of Wuxi City in Jiangsu Province, in order to better serve the complex greening engineer of slope. The results showed that the cohesion and internal friction angle decreased significantly with the increase of soil moisture content, as soil moisture content changed from 15% to 25%. The cohesion and internal friction angle increased significantly with the increase of the dry density when the soil moisture content was 15% and 25%, respectively, but when the soil moisture content was 20%, the cohesion decreased with the increase of the dry density and the internal friction angle remained unchanged.
