目前,土工合成材料在我国的基础建设、农业工程、水利和土壤改造、海洋建设、环境保护工程中具有良好的发展前景。据预测,2000年后我国每年需土工材料2亿平方米。据了解,1998年至2002年我国将新建公路30万千米,其中高等级路3.5万千米;铁路建设投资2450亿元,新建铁路5340千米,铁路运行里程到2002年将突破7万千米;每年整修翻浆路段可达1000千米;长江三峡、黄河小浪底工 At present, geosynthetics have good prospects for development in China’s infrastructure, agricultural engineering, water conservancy and soil remediation, marine construction, and environmental protection projects. It is predicted that after 2000 China will need 200 million square meters of geotechnical materials each year. It is understood that from 1998 to 2002, China will build 300,000 kilometers of new highways, including 35,000 kilometers of high-grade roads; 245 billion yuan will be invested in railway construction, 5,340 kilometers of new railways, and the mileage of railways will exceed 70,000 kilometers by 2002; The reconstructed road section can reach 1,000 kilometers; the Three Gorges on the Yangtze River and Xiaolangdi on the Yellow River
