厦门市西源溪冲沟泥石流危险性评价

RISK ASSESSMENT OF DEBRI SFLOW IN XIYUANXI GULLY,XIAMEN CITY

评价泥石流灾害危险性有助于选择合适的工程措施降低其危害程度。若爆发泥石流,会对主体工程施工和安全运行将造成严重威胁,因此有必要对该冲沟进行调查和泥石流评价。西源溪冲沟内常年有水,沟长7.89 km,流域周长13.31 km,流域面积11.5 km^(2)。泥石流灾害的发生会对下游西源溪村中的人民造成生命威胁,同时也会对工程施工造成巨大的损失,严重危及到了当地的自然经济发展。本文通过对西源溪冲沟进行实际的调查与后期的分析,旨在得出其泥石流易发程度,为今后对当地有关的调查分析提供相关理论依据。

Evaluating the risk of debris disasters helps to choose appropriate engineering measures to reduce the degree of harm.If the debris flow erupted,the construction and safe operation of the main project will cause serious threats,so it is necessary to conduct investigations and mudslide evaluation of the ditch.There are water in Xiyuanxi Chonggou all the year round,the ditch is 7.89 km long,the length of the basin is 13.31 km,and the watershed area is 1l.5 km^(2).The occurrence of mudslide disaster will cause life threats to the people in the downstream Xiyuanxi Village.At the same time,it will also cause huge losses to the construction of the project,which seriously endangers the local natural economic development.In the later analysis,it aims to obtain the degree of mudslides,and provides relevant theoretical basis for future investigation and analysis of relevant local investigations.
