一、前言到目前为止,土工织物主要用作铺垫材科,而没有实际应用到三维结构物中,然而,土工合成纤维土技术恰恰可以应用到三维结构物中。这是一种砂土材料掺入连续不断的合成纤维对土体进行加固的一种方法。实现连续纤维同粒状材料混合的研究是土工织物技术发展的结果。从1979年开始,法国道桥中心研究所主持了土工合成连续纤维加固粒料砂土的研究,试验主要在鲁昂道路试验中 I. INTRODUCTION So far geotextiles have been mainly used as bedding materials, but have not been applied to 3D structures. However, geosynthetic soil technology can be applied to three-dimensional structures precisely. This is a sand soil material incorporation of continuous synthetic fibers on the soil reinforcement method. The research of realizing continuous fiber and granular material mixing is the result of the development of geotextile technology. Since 1979, the French bridge center Institute presided over the geosynthetic continuous fiber reinforced gravel sand research, the main test in the Rouen road test
