高速公路运营期高边坡安全风险评估体系研究

在高速公路运营期间,高边坡失稳破坏时有发生,严重影响运营安全。在大量的工程实践基础上,通过详细研究,提出了一套量化的高边坡安全风险评估体系。体系综合考虑了影响边坡稳定性及失稳后果的各种因素,专人排查并根据具体边坡各影响因素的重要性对其赋予不同的权重,量化出各个边坡的风险分数RS,再结合杭甬高速公路高边坡风险评估工程实例,证明该评价体系行之有效。

Study on Safety Risk Assessment System for High Slope of Highway in Operation

High slope may be failure from time to time during the operation of highway, endangering the safety thereof. Based on a large amount of engineering practice, a completed quantitative safety risk assessment system was proposed through studies. This system took the factors influencing slope stability and consequence of failure into account comprehensively, checked and assigned different weight values to each factor according to its importance specially, thus quantized every risk score RS of slope. Combined with the practice of risk assessment for high slope along Hangyong Highway, this system was validated and proved to be effective.
