聚丙烯土工带用于加筋土工程是我国首创的。迄今为止已使用十余年,国外尚无应用聚丙烯土工带的报道。由于聚丙烯土工带(以下简称土工带)适合我国国情,制造简单,原料丰富,生产成本较低,因而在我国已大量推广使用。在已建成的加筋土工程中,80％以上均采用土工带。在我国公路加筋土工程中,95以上的工程均使用土工带。随着加筋土工程在我国的迅速推广,土工带的用量还将与日俱增。因此对于土工带的进一步研究具有非常重要的现实意义。人们对土工带的优点已有充分
Polypropylene geotextile used in reinforced earthwork is our country’s first. Has been used so far more than ten years, there is no report of the use of polypropylene geotextile abroad. As polypropylene geotextile (hereinafter referred to as geotextile) suitable for China’s national conditions, manufacturing simple, rich in raw materials, lower production costs, which in our country has been widely promoted. In the reinforced earth project has been completed, more than 80% are used geotextile. In our country road reinforced earthwork, geotechnical belt is used for more than 95 projects. With the rapid promotion of reinforced earthwork in China, the amount of geotextile will also increase with each passing day. So for the further study of geotapes has very important practical significance. People have the advantage of geotextiles have been fully
