摘要:
云南省不同尺度地质环境脆弱,公路作为带状建筑展布于复杂、脆弱地质环境中,公路水毁时空分布规律是复杂的。运用统计分析和实地调查方法,分析云南省公路水毁时空分布和发展态势。突降暴雨易即时诱发公路水毁,公路水毁具有单点性;普降暴雨也易即时诱发公路水毁,公路水毁具有带状性,水毁链效应显著;降雨强度不高时,公路水毁发生略有滞后性。云南省公路水毁主要发生在6—8月,7月是高发期;在20世纪,公路水毁周期一般为2～3 a,21世纪公路水毁周期一般为4 a。滇西公路水毁密度大于滇东,滇北大于滇南,滇中公路水毁主要分布在滇中边缘地带;公路等级越低,公路水毁越严重;不同地区公路水毁种类有差别。云南省公路水毁目前仍...
Abstract:
Different scale geological environment in Yunnan province is fragile. As belts the highways distribute in complex and fragile geological environment, spatialtemporal distribution of waterwasterings of highways is also complex. In this paper, spatialtemporal distribution and development situation of waterwasterings of highways in Yunnan Province will be analyzed through methods of statistic and field investigation. Sudden rainstorms reduce waterwasterings of highways easily, one characteristic of waterwasterings of highways is singlepoint. Widespread rainstorms also can reduce waterwasterings of highways easily, the characteristic of waterwasterings of highways is zonal，waterwasterings of highways chain effect is also significant. When it didn’t rain heavily, waterwasterings of highways would appear hysteretic character. Waterwasterings of highways in Yunnan province usually happen from June to August and it gets to peak period in July. In the 20th century, waterwasterings of highways cycle is about 2 to 3 years and in the 21st century, waterwasterings of highways cycle is about 4 years. Density of waterwasterings of highways of in the west of Yunnan is obviously heavier than that in the east of Yunnan and that in the north of Yunnan is heavier than that in the south of Yunnan. Waterwasterings of highways in central Yunnan usually happen at the edge of middle Yunnan.The lower the highway classification, the more serious the washouts of road. Characteristics of different areas of Yunnan are different. Waterwasterings of highways in Yunnan province are still developing at present.
