- 为研究在用地受限条件下高填路堤的边坡支护形式,基于渡口河天然气净化厂进厂道路高填方路堤项目,开展了对高度20 m对拉式加筋路堤的边坡结构、施工工艺和质量控制方法及应用效果等方面的研究，用数值模拟计算对比分析了对拉式加筋路堤的应力和加筋材应力的变化规律。研究结果表明,对拉式加筋高路堤占地少,整体稳定性好,在占地或其它地形受限条件下,采用对拉式加筋路堤是较好的解决方案;加筋改变了路堤的滑面形态,减小了路基坡体内剪应力,从而提高了路基的稳定性。结论认为，对拉式加筋陡边坡高路堤具有安全性、经济性和较好的应用效果,具备推广价值。
To investigate slope support methods for high-fill embankments under land-use constraints, this paper presents the study on slope structure, construction technology, quality control methods, and application effects of a 20 m high counter-pull reinforced embankment for the access road of Dukouhe Natural Gas Purification Plant. The study shows that the counter-pull reinforced high embankment requires less land and exhibits good overall stability. Under conditions of limited land availability or other terrain constraints, the counter-pull reinforced embankment is a preferable solution. The reinforcement alters the slip surface morphology, reduces shear stress within the embankment slope, and thereby enhances embankment stability. It is concluded that, the counter-pull reinforced steep slope embankment demonstrates safety, economy, and favorable application performance, making it worthy of wider adoption.
