淤地坝是水土流失地区治理沟道侵蚀的主要工程措施,坝地亦因土肥水足产量高而倍受群众青睐。但是,在以往的淤地坝设计中,偏重于考虑工程安全,而对坝地利用及其防洪保收考虑甚少,加之黄土高原地区雨热同步的自然特点,致使坝地的保收率普遍较低。生产实践中,往往需采取一定的技术措施确保坝地的防洪保收。
Warping dams are the major engineering measures to control channel erosion in soil and water loss areas. Due to the high yield of soil, fertilizer and water, dams and dams are much favored by the public. However, in the past silt dam design, emphasis was placed on considering the project safety while little consideration was given to the dam land utilization and its flood control and collection. In addition, the natural characteristics of rain and heat synchronization in the Loess Plateau resulted in the widespread acceptance of the dam land Lower. Production practice, often need to take certain technical measures to ensure dam flood protection.
