历年洪水都会对我们的各类工程形成一种威胁和考验,过去人们已总结过一些经验和教训,但年代久了,也就习以为常停滞不前了。就防洪抢险来说,一提备料就是袋子(草袋为主)、木桩、铅丝,别的却很少。土工合成材料问世以来,也仅仅停留在化纤编织袋代替草袋而已,并没有发挥出土工合成材料这一种新技术的力量。1995年辽宁、吉林两省的暴雨来得十分突然,洪水凶猛,使人防不胜防。尽管水库发挥了很大作用,保住了下游大中城市,然而铁路公路及其它水毁工程却很多,被淹的村庄农田很多,因此这里

However, in the past, they have often stagnated. In terms of flood control and rescue, a mention of preparation is the bag (grass bag-based), stakes, lead wire, but few others. Since the advent of geosynthetics, but also just stay in the chemical fiber woven bags instead of straw bags only, and did not play a synthetic geotextile force of this new technology. In 1995, the torrential rains in Liaoning and Jilin Provinces came suddenly and suddenly. The flood was fierce and hard to prevent. Although reservoirs have played a significant role in keeping downstream large and medium-sized cities, there are many railroad and other water-damaged projects, and many flooded villages have farmland, so here
