【摘要】 自然环境条件对公路工程的影响,主要体现在路线选取、路基强度和稳定性、路面稳定性和耐久性、公路主要自然病害(包括冻融、翻浆、雪害、风沙害、崩塌、滑坡和地震灾害等)、施工条件和养护运营环境等5个方面,分析自然条件和公路工程的关系,提出公路区划中地质地貌环境参数和水热状况环境参数,阐述了环境参数的提出过程,为新疆公路自然区划三级区的划分提供依据。更多还原

【Abstract】 The influence of the natural environment conditions upon the highway engineering mostly incarnate five aspects:route selection, stability and durability of pavement and subgrade, main highway natural diseases(including freezing and thawing, frost boiling, snow disease, dilapidation, silde, cataclysm and so on), construction conditions and road maintenance etc. In this paper. Through analyses of relations between natural environment conditions and highway engineering from the five aspects, the parameters of geologic and geomorphological environment and water and caloric environment are put forward, the process to advance enviorment parameters is expounded and the gist of the tertiary natural zoning offerd.更多还原
