Summary The large underground power chambers of Ertan Hydropower Station will be built near the abutment on the left bank in a region with high initial stresses. In this paper, a statistical analysis is presented for the phenomenon of core disking in the dam site. On the basis of a number of stress measurements, the region of the river valley could be divided into three different geostress zones. It is shown that there exists a rather high horizontal stress of up to 30 MPa, and even over 60 MPa at the bottom of the river bed. A least square method has been introduced to get a continuous field of stress, which approximates the variable measured stress data.
