路堤饱和软土地基初始孔压分布及沉降分析

变形和稳定性问题是岩土工程中需要解决的两个主要问题，尤其是在软土地基上修建公路，这两个问题就更加突出。从工程实用角度出发，将饱和软土地基视为Biot介质，假定路堤荷载瞬时施加，求得了地基中初始超静孔隙水压力的分布，以及有效应力的分布，进一步求得瞬时沉降和固结沉降。分析了压缩层厚度和土骨架泊松比对瞬时沉降和固结沉降的影响，为施工前填土方量计算、填筑结束后地基超静孔隙水压力分布和沉降计算提供了依据，其计算表达式简洁，便于工程应用。最后对一个工程实例进行了分析。

The impact of using chilled water storage systems on the performance of air cooled chillers in Kuwait

In the air conditioning (AC) industry chilled water storage (CWS) systems are one form of cool thermal storage technology that can be used to time shift the electrical load of the system from the peak day periods to off peak night time periods. In this paper the data for the actual exported and generated electrical energy obtained for the power stations in Kuwait has been used to estimate the electrical energy consumption and the peak electrical load of AC systems. Since the chiller in an air cooled AC system represent more than 75% of the total electrical power consumed by an AC system during the peak demand period, the impact of using CWS systems with alternative operating strategies including partial (load levelling), partial (demand limiting) and full load has been investigated. In our conclusions we estimate that approximately 45% of the total annual exported electrical energy is consumed solely by AC systems as a result of the very high ambient temperatures occurring between March and October. Furthermore, it is estimated AC systems represent about 62% of the peak electrical load. The results demonstrate that CWS can reduce the peak electrical load of a chiller in an air cooled AC system by up to 100% and reduce the nominal chiller size by up to 33% depending upon the operating strategy adopted. This is achieved with only a 4% increase in power consumption of the chiller for all CWS strategies except for full storage where the energy consumption actually decreases by approximately 4%.
