%X Yunnan is located in the plateau mountainous area with varying hydrological meteorological condition, steep topography and complex engineering geology condition. When conventional energy dissipation work does not adapt, dissipation well is a feasible alteration. However, the hydraulic characteristic of dissipation well with inclined inlet is rarely studied. In this paper, the mechanism of  water force in the presence of submerged jets in  dissipation wells with inclined inlet and outlet   under a certain longitudinal slope condition is examined based on turbulence jet division in the well. And furthermore the expressions of the maximum velocity of jet along the flow and the time-averaged impact force on the shaft wall in impact zone under the oblique inlet condition are deduced. The parameters of the semi-empirical formula under longitudinal slope condition are determined in association with hydraulic test. The research results offer reference for the design of similar projects.
