某机场加筋土挡墙稳定性分析

STABILITY ANALYSIS OF REINFORCED RETAINING WALL IN AN AIRPORT

采用有限元强度折减法对某机场边坡治理工程中采用的土工织物加筋土挡墙进行分析计算,着重对土工织物筋带参数和填土抗剪强度等参数进行了分析。分析结果证明,采用土工织物加筋土挡墙的设计方案可有效解决该边坡产生滑坡的潜在危险,保证工程稳定性达到设计要求,并且所采用的等长均匀布筋方式是该边坡加筋最佳布筋方案。填土的抗剪强度和筋材的长度的变化对安全系数影响比较明显。对有限元强度折减法进行加筋土挡墙的计算能保证加筋土的结构稳定性,提升设计安全性和可靠性,节约工程开支。

In this paper author has used the finite element method strength reduction for analysis and calculation of geotextile reinforced retaining wall slope engineering in an airport,it focuses on analysis of geotextile reinforcement parameters and shear strength of soil.As can be seen from the calculation results.The geotextile reinforced soil retaining wall design scheme can effectively solve the potential risk of landslide slope,it can also.Ensure that the engineering stability to meet the design requirements,the same length of uniform distribution is the best reinforcement scheme of this project.The influence of the shear strength and the length of the reinforced material on the safety coefficient is obvious.In addition, finite element method strength reduction calculation for the geotextile reinforced retaining wall,it is able to make up for the deficiency of traditional design method,improve the design of safety and reliability and save engineering cost.
