对于黄河中下游冲积平原砂性土层深长桩桩侧极限摩阻力问题,根据该地区的地质特性、采用有限元
软件ABAQUS对大量不同参数的深长桩进行了建模分析,结果表明:桩顶荷载与桩侧摩阻力近似呈线性关
系,桩长、桩径、桩-土界面条件、桩周土的力学性质等对桩侧摩阻力影响程度不同.根据有限元计算结果推导
出了砂性土层深长桩桩侧极限摩阻力的计算公式,用其对工程实例进行验算,并将计算结果与静载试验实测
结果进行了对比,二者吻合较好,说明有限元建模方法、参数设置及结论可靠,计算公式较准确.该研究可为该
地区深长桩的优化设计提供参考.

In order to improve the thermal environment and reach the energy efficiency goal of rural house in Ningxia Hui
Autonomous Region,the paper investigates a typical traditional vernacular,analyzes the index of heat loss of building envelop
and discovers the main weak part in the building affecting on the energy consumption.Combining with the local conditions
of climate and economy,this paper put forward the integrating designing project,including the function layout,
room combination,solar energy utilization and construction of building envelop.A new project for improving the indoor
thermal comfort and saving energy was given in this paper.The index of heating loss of two rural buildings are calculated
in order to verify the effectiveness of the new project.At the same time,it is bproved that the improvement of the thermal
environment and 65%energy efficiency goal can meet with by appropriate architectural designs.
