前言东山灌渠是川西平原上重要灌溉渠之一。它对川西平原上的农业增产和实現农田水利化起着极大的作用。自渠道建成三年多来,边坡破坏十分严重。仅在地貭学院附近二至三公里的范围内,就有大小滑坡近百个之多,严重地影响了渠道正常使用,同时也威胁着周围工农业建设和人民生命財产的安全。每年对渠道的破坏边坡进行修理,其工程量也很大,而且耗费了大量人力物力,往往还不能彻底根治。
Dongshan Irrigation Drainage Channel is one of the important irrigation channels in the western Sichuan Plain. It plays an important role in boosting agricultural production and realizing water conservancy in the western Sichuan Plain. Since the channel was built more than three years ago, the slope damage is very serious. In the area of only two to three kilometers near Di Tu College, there are nearly 100 large and small landslides, seriously affecting the normal use of the channels and threatening the safety of industrial and agricultural construction and people’s lives and property. Every year, the destruction of the slope of the channel is repaired, and the amount of engineering is also very large. Moreover, it takes a great deal of manpower and resources and can not be completely eradicated.
