After the completion of the reservoir, start storing flood, cut from the Pi River flood, the Huaihe River flood peak reduction. Geology of dam site The dam area is water rock, metamorphic rocks and the intrusive igneous rocks, two. Aqueous metamorphic rocks from top to bottom were gray quartzite, schist, quartzite and SLATE black white quartz, thickness from a few meters to tens of meters from angle of 40-55 degrees. The igneous plutonic rock series are granite porphyry, and they are interspersed with each other in the form of dykes and cross beds. Granite, black quartz slate, dense and solid, resistant to high pressure. Most of the arch dam foundations are placed on this kind of rock. In addition, a few of them are placed on the gray quartz, quartz and schist layers with poor lithology. The granite weathering of the dam foundation of the West Coast gravity dam is very strong, and it has been properly handled during construction. Generally speaking, the multi arch dam foundation is very stable and safe. Before 3, the reservoir project started from the nearby Foziling Pi River to the east coast area terrain.
