加筋土挡墙设计方法对比与实例分析

Comparison of design methods for reinforced soil wall and example analysis

摘要: 在工程实践中,国内外土工合成材料加筋土挡墙的设计方法存在差异。基于对国内外加筋土设计方法和工程实践的分析和认识,分别以我国相关设计规范和北欧加筋土结构设计指南为准则,以湖北省某高边坡加固工程为案例,完成了土工合成材料加筋土挡墙的详细设计方案。根据设计计算结果,对比两种设计体系在加筋土挡墙设计理论、设计参数的取值、验算方法等方面的差异。并对产生这些差异的原因进行了分析,为我国土工合成材料加筋土设计规范修订和工程实践提供借鉴。

Abstract: As to the design methods for geosynthetic reinforced soil(GRS) walls,there are some discrepancies between the domestic and the overseas codes in engineering practice.Based on the analysis and knowledge of the design methods for GRS Wall and GRS Wall practice both at home and abroad,and taking the high filling wall design in Hubei Province as an engineering case,a detailed GRS Wall design process according to the Chinese related design code and Nordic reinforced soil guideline is carried out sepa...
