新疆公路三级区划设计参数的研究

在现行自然区划的基础上，从设计和施工的需要入手，提出了建立在新疆公路三级自然区划基础上的新疆公路设计参数：土基回弹模量E0和加州承载比CBR(California Bearing Ratio)。论述了设计参数资料收集的数据内容及应注意的问题，采用数理统计方法从收集的资料数据中确定不同土质在不同自然区的E0值、CBR值均值的上、下限，并对其进行了相关性分析。通过分析建立了新疆各三级自然区较精确的设计参数数值的推荐范围，并对取值作出详细说明，为新疆地区的公路设计提供了可靠依据。

Research on design parameter of the third rank division for highway in Xinjiang

Based on the current natural division,commenced from the demand of design and construction,authors put forward the highway design parameter of Xinjiang: the modulus of resilience of roadbed E_0 and CBR based on the third rank division.A concise presentation of the content and the problem of the design parameter data collections which should be noticed is given.Based on the collected data and combined the adoption of mathematics statistics method,authors confirm the up,under limit about the E_0 and CBR of the different soil quality in the different and natural area,and process relativity analysis about the design parameter.The design parameter scope through analyzing each third rank natural area in Xinjiang is established and value is proved in detail which can directly put forward calculation for the highway design in Xinjiang.
