This paper studies the stress of gravity dam heel with careful numerical simulation, and analyses the effect of the variety of the elastic modulus of homogeneous or non-homogeneous foundations on the principal tensile stresses of gravity dam heel. The conclusions are as follows:① When the elastic modulus of homogeneous dam base and variated element in the critical place is changed with the same the fluctuation, the effect on the dam heel stresses caused by the latter is much more prominent than the former one.

本文通过精细网格模拟研究了重力坝坝踵应力情况，就均质坝基和非均质坝基弹模变化对坝踵主拉应力的影响，得出了如下结论：①均质坝基弹模与非均质坝基敏感区域的变异单元弹模变化相同的幅度，非均质情况引起的坝踵应力的变化远大于均质情况。

The maj or obj ect of this paper is the medium.small size concrete dams that have been used for many years.They have the characteristic that the alteration of water height of reservoirs is unobvious and the dams, displacements are affected mainly by temperature.With a case,the method of stepwise regression is used to analyze the vertical displacement prototyDe observed data.Then regression equation is established,the relation of dam,s displacement with hydraulic pressure、temperature、time effect is analyzed and the displacement change rule is obtained,the dam'S displacement onlv dependent to temperature is received.According to the theory of Finite Elements Method,the quasi-stationary temperature field formula and temperature stress formula are deduced.The QTP program and TFEM3D program are written with FORTRAN.The same case is calculated through QTP program to solve the quasi-stationary temperature and through TFEM3 D program to solve the dam'S displacement and find tlle dam,s deformation rule.This rule is accordant with the regression,S resuIt.

本文主要针对运行期间库水位变化很小、坝体的位移主要受温度变化影响的中小型混凝土坝，结合工程实例，采用逐步回归的方法对垂直位移原型观测资料进行分析，建立回归方程，分析坝体位移与水压、温度、时效之间的关系以及位移变化规律，分析结果坝体位移只与温度有关，而基本上不受库水位变化和时效的影响；根据有限元原理推求了混凝土坝准稳定温度场公式和温度应力公式，利用FORTRAN语言编制出QTP准稳定温度场程序和TFEM3D位移场程序，对大坝的温度场和位移场进行计算，求出坝体结点的变温值和坝体结点位移值以及单元应力分量，分析得到大坝的变形规律与实测资料以及回归统计变形规律一致，说明对坝体准稳定温度场的研究是正确的。

Some questions such as disqualification dam,many cracks in developing dam body,disperse-impregnation in the downstream slope of dam,forming ascending spring owing to marshization in dam back,wadding educts coming from drainage ditch and rearing pond and a lot of seepage amount were occurred.

陡坡水库存在大坝质量差、坝体发育大量裂缝、背水坡出现散浸现象、坝后沼泽化并形成一上升泉以及排水渠和鱼池有絮状析出物、渗漏量增大等问题，这些异常现象都是由坝体及坝基渗流引起的。

The dam body construction working procedure relates the construction cost of dam The research indicated Counter-construction is good to the strain of CFRD The research indicated the distribution of primary and secondary stone body is important to cost of dam the secondary stone body relate with the strain of dan when dam withstand the pressure of water Work in this thesis will play a active role in the research on CFRD.

坝体的施工工序关系到大坝的施工成本和坝体变形状况，通过对面板堆石坝堆石体施工方法的探讨，得出反抬法施工对避免面板堆石坝不协调变形有积极作用。面板堆石坝的结构分区也是影响面板堆石坝工程造价的一个重要考虑因素，结构分区的重点研究是次堆石区的分布范围。结合水布垭面板堆石坝的研究表明次堆石区的材料对面板堆石坝蓄水有比较大的影响。
