泥石流柔性防护系统破坏原因分析与设计对策

泥石流柔性防护系统对于中小型泥石流有很好的防治效果,但在实际工程中很容易发生破坏。为研究泥石流柔性防护系统破坏原因,介绍了泥石流柔性防护系统的构成与优势、破坏原理、破坏形式,并针对四川省道217某段公路改建工程的泥石流柔性防护工程,分析了系统的设计、构件、基础等方面的问题,得出主要破坏原因是设计不合理,未完全按照定型化设计,基础发生破坏,构件发生破坏。同时对泥石流柔性防护工程的设计提出了一些建议,以期提高其拦截能力。

Failure Cause Analysis and Countermeasures Design of Flexible Debris Flow Protection System

Flexible debris flow protection system has good control effects for small and medium debris flow ,but it is easy to be destroyed in practical engineering .In order to study the failure reasons of the flexible debris flow protection system , the structure and advantages of the flexible debris flow protection system ,the failure principle and the failure form are in-troduced .And for the Sichuan provincial road 217 a section of the highway reconstruction project of debris flow flexible protection system ,the existing problems in the design ,components ,foundation are analyzed .The main reason is the un-reasonable design ,the system is not fully in accordance with the standard design ,the basis of destruction ,component damage .At the same time ,some suggestions are proposed to design the flexible protection engineering of debris flow in order to improve its blocking ability .
