解决好沉降问题是保证高速公路质量的关键。本文着重介绍掌握沉降规律的方法并认为:计算最终沉降以公路系统公式为好,推算最终沉降以指数曲线延伸法为佳。根据沪嘉高速公路的资料分析,提出了初步的估算沉降经验公式,并对工后沉降发展作了探讨。
Solving the settlement problem is the key to guaranteeing the expressway quality. This article focuses on the method of grasping the law of settlement and holds the opinion that it is better to calculate the final settlement with the formula of highway system, and it is better to calculate the final settlement by exponential curve extension method. According to the data analysis of Shanghai-Jiaxing Expressway, a preliminary empirical formula for estimating settlement is proposed and the settlement of post-construction settlement is discussed.

青藏高原积雪变化对陆面能量水分传输过程有重要影响。本文采用RegCM4.7-CLM4.5模式模拟了高原及其周边地区31年的积雪过程,通过对模拟结果的EOF分解,发现高原积雪的时空变化主要呈现为高原主体与高原东北部反相、东西反相以及南北反相3种模态,方差贡献率分别为30.05%,14.86%和8.48%。合成分析显示,高原积雪异常中心与高原的主要积雪区较为一致,积雪深度与积雪日数均有减小的气候倾向,
