GFRP筋在深基坑边坡土钉支护工程中的应用

摘要

土钉支护在我国基坑边坡支护工程中已广泛使用。对由树脂和玻璃纤维复合组成的玻璃纤维筋（GFRP筋）作为土钉材料,其性能、外观、规模等要求进行了介绍,明确了GFRP土钉支护设计要求。结合郑州市轨道交通某单项工程的工程实例,探讨分析了高边坡土钉支护中采用玻璃纤维筋的经济性和适用性。%Soil nailing has been widely used in foundation pit slope supporting engineering in China. The paper introduces the performance, appearance, size and other requirements of soil nailing made of the resin and glass fiber composite, and clarifies the GFRP soil nailing design. Combined with the traffic of Zhengzhou city orbit a single-item engineering example, discussion and analysis of high slope soil nail supporting uses a glass fiber reinforced economy and applicability.
