The full length of this road is 5721 meters, including six turning points and twelve upright curve, according to the requirement of the letter of assignment, we should fulfill the missions as follows: Route plane design, route vertical section design, roadbed design, road surface framework design (asphaltum road surface and concrete road surface) as well as selecting one kilometer for road surface drainage design, route transect design together with cubic meter of earth and stone.

此公路全线5721米，共设有六个转点，十二个竖曲线，根据设计任务书的要求，本次设计将要完成以下任务：路线平面设计，路线纵断面设计，路基设计，路面结构设计(沥青路面和水泥混凝土路面)以及选取一公里的路线进行路面排水设计，路线横断面设计，并进行土石方的调配。

Astrophysicists working with groundbased detectors at the South Pole and balloon-borne instruments are closing in on such structures,and may report their findings soon.

The model includes that the relationship between median diameter, as well kinetic energy, of raindrop and rainfall intensity obeys logarithmic function, the critical slope degree of soil erosion is 38.4°～43.0° in test area and the best multiple index of rainfall erosivity value is /100. Employing the prediction model, the soil erodibility value, the accelerated value of excavation slope, roadbed slope, construction site, borrow pit, service road and other temporary occupation land and the loss-spoil ration of waste pile were examined. Finally, the integrated soil and water conservation measures in highway construction project have been suggested.

从而建立了凉山州天然降雨雨滴中数直径与雨强的关系和降雨强度与动能的关系，分析了高速公路引起水土流失的侵蚀性降雨标准、侵蚀转折坡度及不同流失区流失量的大小关系，给出了高速公路水土流失预测模式中降雨侵蚀力尺值的最佳复合指标，估算出路堤边坡、路堑开挖边坡、路基、临时施工用地、取土场、便道和其它临时占地的可蚀性K值、加速侵蚀系数A值以及的弃土场的流弃比B值，最后针对高速公路不同防治区水土流失特点提出了相应的综合防治措施。

In this paper, the factors that may cause crack breaking of concrete pavement of several built highways were analyzed systematically and thoroughly. From analysis to site experiments and calculation, it is believed that crack breaking is mainly caused by factors as follows: 1 、 Unqualified sedimentation and losing stabilization of the roadbedinduced crack in the early; 2、 Construction technology、 materials and incorrect treatment methodswere adopted;3 、 Crack breaking induced by thermal stress; 4、 Water cant circulate makes crack cause;With regard to the afore-mentioned problems, corresponding preventive measures, qualified control indices and site control approach are presented based on analysis theory and site experiments.

本文在全面系统地分析已建成的高速公路水泥混凝土路面产生的原因的基础上，通过现场试验及计算分析，确定了高速公路水泥混凝土路面裂缝的主要影响因素有以下几个方面： 1、路基的不均匀沉降、失稳是早期裂缝产生的主要因素； 2、施工工艺、材料问题及养护方法不当； 3、温度应力产生的裂缝； 4、排水不畅影响裂缝产生；针对上述问题，通过理论分析及现场数据提出相应的质量控制目标、现场控制方法。
