%X Rock-soil aggregate is a special kind of engineering geological body, its mechanical characters are very complicated. It has huge influence on engineering projects. For it has very complicated physico-mechanical properties and the collection of its samples is very difficult, the study has not been sufficient so far. In order to make more study on the distortion and destruction characters of the rock-soil aggregate, six test sites on the right bank of Longpan in Tiger-leaping Gorge reservoir area are selected. In these six test sites, six horizontal push-shear in-situ tests were done, which include three non-water immersion tests and three water immersion tests, and some significant results were obtained. Through these in-situ tests, the strength characteristics and the complete stress-strain curves under various states were obtained. At the same time, by analyzing the group of block size and the three-dimensional sliding face, the mechanism of distortion and destruction of rock-soil is discussed to explain why the friction angle is on the high side in such kind of special geological body, and the conception of the average sliding surface which is used in calculating the strength parameters and the conception of the key diameter which is very important in determining the value of the cohesion are put forward. At the end, a reasonable reference value on the strength parameters of rock-soil aggregate in the study area is proposed to establish the foundation of the 3D slope stability analysis.
