Abstract

Flexible protective network system is widely used to prevent and control dangerous rockfall disasters along the mountain railway. Rockfall accidents caused by insufficient design protection capacity, product quality defects and poor construction quality occur from time to time. The safety and reliability of flexible protective network system engineering should be paid attention to. This paper introduces the common problems of flexible protective network system engineering, and expounds the method of reliability investigation and evaluation of flexible protective network system engineering. The relevant data and calculation formula of this paper are provided by the flexible structure research and development center of Southwest Jiaotong University
