【摘要】 在山区公路建设中,沿河公路路基水毁不仅影响路面的稳定性和正常使用功能,而且给公路后期的养护带来很大的困难。通过对大量调查资料的分析归纳,结合相关理论知识和模型试验,研究分析了山区沿河公路路基水毁形式、特点及原因,提出沿河公路路基冲刷防护应遵循"顺应水势、因势利导"的原则,并提出几种工程防治措施,可为工程设计人员在山区沿河公路路基设计及其水毁治理时提供参考。更多还原

【Abstract】 The washout of subgrade alone river not only influences the stability and normal use of pavement, but also brings the great difficulty of late maintenance of highway. According to thorough investigation and the knowledge of relevant theory and model test, this paper studies and analyzes the washout forms, characteristics and reasons for the subgrade along river and puts forward the principle-"Adapt to the Flow of Water and Make the Best Use of the (Situation")-which should be observed in the washout protection of the subgrade of the highway along the river. Also it proposes several prevention measures, which can be used for reference by the project designers when designing the subgrade of the mountain highway along the river and bringing its washout under the control.更多还原
