The basic profile of gravity dam refers to the triangle profile that the dam body meets the stability and strength requirements under the three main loads of self weight, hydrostatic pressure (water level is flush with the dam crest) and pressure rise. Minimum workload. Under the conditions of known dam height h, water pressure P, shear strength parameters F, C and uplift pressure U, according to the requirements of anti sliding stability and strength, the minimum triangular section size of the project can be obtained.<br><br><br><br>According to the engineering experience, the slope of the upstream dam is generally n = 0-0.2, usually vertical, or the upper part is vertical, and the lower part is inclined to the upstream. The slope of the downstream dam is m = 0.6-0.8; the bottom width is about 0.7-0.9 times the dam height.<br><br><br><br>According to the requirements of traffic and operation management, the dam crest shall have sufficient width. In order to prevent waves from crossing the dam crest romantically, a certain superelevation should be kept above the static water level.
