随着混凝土面板堆石坝技术的不断发展,我国面板堆石坝已成为主流坝型之一。堆石坝坝体填筑量大,需要有较大的填筑料料场,填筑料料场选择是否适当,不仅关系到工程造价,更能有效降低工程建设对生态环境的影响。通常情况,填筑料料场往往选择在库区外,料场开挖后对环境造成永久性影响,局部造成水土流失。若将料场选择在库区内,且在正常高水位以下,可以在很大程度上减少料场开挖后造成对环境的影响,有效防止局部水土流失的问题,并在一定程度上降低工程建设投资。
With the continuous development of concrete faced rockfill dam technology, China’s rockfill dam has become one of the mainstream dam types. Due to the large amount of filling of rockfill dam, it is necessary to have a larger filling material yard, and whether the choice of filling material yard is appropriate, not only relates to the project cost, but also effectively reduces the impact of the project construction on the ecological environment. In general, filling material yard is often selected outside the reservoir area, the excavation of the yard after the permanent impact on the environment, resulting in soil erosion. If the material yard is selected in the reservoir area and below the normal high water level, the environmental impact caused by the excavation of the material yard can be greatly reduced, the problem of local water and soil loss can be effectively prevented, and the project can be reduced to a certain extent Construction Investment.
