| 摘 要： | 综合既有线挡墙安全等级划分的现状,提出了挡墙安全评估四级分级法;并考虑浆砌片石挡墙的特殊性,在传统的安全评估单元中,新增了自然因素与外部环境项,针对新的评估单元引入定性与定量评估相结合的综合评估方法,提出了综合安全等级的概念.综合安全评估法较传统的定性安全评估方法更细致全面,且能量化,可为浆砌片石挡墙安全评估作参考.

| Abstract: | This paper,depending on the status quo of security level classification for retaining wall of existing line,proposed a four-level hierarchy method for the safety assessment related.Considering the particularity of mortar rubble retaining wall,natural factor and external environmental item were added in the traditional unit of safety assessment; and then for such new unit,the comprehensive evaluation method combining qualitative and quantitative analysis was introduced,by which the concept of comprehensive security level was put forward herein.The new comprehensive evaluation method,compared with the traditional qualitative evaluation method,is more specific and comprehensive with the ability of quantization,which may be referenced in the safety assessment for mortar rubble retaining wall. |
