摘　　要：运用已有野外现场调查与室内模型试验资料,研究了山区小桥涵抗水灾能力评价指标及评价方法。分析了导致山区公路小桥涵水毁的因素,提出了小桥涵抗水灾的评价指标,并运用模糊数学的方法建立了山区公路小桥涵的致灾因子与其抗水灾能力的关系,提出了评定山区公路小桥涵抗水灾能力的评价指标和综合评价方法。Utilizing the data of field investigation and indoor model test, the paper makes research on the indexes for estimation of flood - resistance of the small culvert in mountain area and the estimating methods. It analyzes yet the factors leading to water injury of it,puts forward the indexes for estimation of its flood - resistance, establishes the relation of factors causing the flood to it with its flood -resistance by fuzzy math method, finally presents synthetic estimating methods for its flood -resistance.
