    This paper is confined to a discussion of prevention of seepage from earth dams by means of blankets upstream which is considered to be a method for greater,quicker,better and more eco- nomical results.The following main problems are included: 1.Ideas of possibilities of piping through foundation soil and resistance of soil to percola- tion,and their effects on calculations of the lengths of blankets; 2.Calculations of economical and safe lengths of blankets and discharge of seepage; 3.Determination of the line of saturation behind a inclined wall and the equipotential line below a blanket. The choice of the minimum blanket length depends in the main on the following conditions: 1.The seepage gradient through the dam foundation below the blanket jo is lower than or equal to the allowable gradient for the soil in the dam foundation(in consideration of no de- formation in seepage); 2.The discharge of seepage per unit width q is lower than or equal to the allowable design discharge (in consideration of storage and exploitation of water energy). Based on the subdivision principles of and the above-mentioned con- siderations,the following equations are derived.For the first condition,the blanket length is calculated from Equation(15);and that for the second condition,Equation(14). When the blanket length is known,the discharge of seepage can be calculated from Equa- tion (18). The blanket thickness is calculated by Equation(25). The 72 experiments made in the laboratory show that the formulas presented in the paper appear to be for the present more accurate than that of other scholars at home and abroad. The theoretical analysis and experiments may lead to the following important ideas regarding prevention of seepage by means of blankets: 2.The less the permeability of a blanket(k_0/k_n>5000)is,the greater its effect of seepage prevention will be,and vice versa; 2.Independent of the permeability of a blanket,there exists the idea of“effective blanket length”,i.e.,for a length larger than the effective length,the effect of seepage prevention of blanket is its permeability increases. 3.It is impossible for a blanket of stronger permeability(independent of length)to do as well as that of weaker permeability(with respect to discharge of seepage).Thus the weaker the permeability of blanket,the better and the value of k_0/K_n should be higher than 2000 at least.

    本文指出土坝上游用铺盖防渗是一种符合多、快、好、省的方法.本文主要研究了下列问题:1.介绍基础土壤的管涌可能性及其所谓抗渗强度的概念,并讨论它们对设计铺盖长度的影响;2.讨论了经济安全的铺盖长度、厚度及渗流量计算;3.确定斜墙后浸润线的位置及铺盖下等势线的分布.选择最短铺盖长度,主要取决于下面两个条件:1.铺盖下坝基渗透坡降 j_0小于或等于坝基土壤的尤许坡降(以不发生渗透变形为原则);2.单宽渗流量小于或等于允许设计渗流量 (以蓄水水能利用为原则).根据巴夫洛夫斯基的分段法原理及上述原则得到下列计算公式.铺盖长度计算:表示第一个条件的计算公式为(15)式;表示第二个条件的为(14)式.给定了铺盖长度后,渗流量按(18)式计算.铺盖的厚度按(25)式计算.从72个试验资料证实本文所建议的计算公式在目前说来,较其他国内外学者的公式精度高.从理论和试验研究结果可得铺盖防渗的几点重要的概念:1.铺盖的透水性愈小(k_0/k_n≥5000)防渗的效用也就愈大,反之防渗的效用则很小.2.不管铺盖的透水性强与弱都存在着“有效铺盖长度”的概念,即铺盖的长度如大于有效铺盖长度时,它的防渗作用不显著.“有效铺盖长度...

NEXT, THE IMPEDANCE MATRIX OF ROTOR IS OBTAINED BY USING THE METHOD OF TRANSFER MATRIX AND MODAL ANALySIS. LAST, THE IMPEDANCE MATRIX OF FOUNDATION IS AOQUIRED IN ACCORDANCE WITH THE THEORY OF ELAS TIC HALF—SPACE. BY MEANS OF ANALYSING BEARING—PIL LOW BLOCK THE RO TOR CONNECTS WITH THE FOUNDATION, THUS THE SYSTEM EQUATION AND EIGENFUNCTION IS OBTAINED. THE STPIBILITy PROGRAMME IS COMPILED ON THE BASIS OF THE A BOUE—MENTIONED METHOD, AND THEN THE OIL OSCILLATING APPARATUS IN ZHENGZOU ENGINEERING RESEARCH NSTITUTE IS CALCULATED. THE CALCULATION RESULT IS THAT SYSTEM STABILITY IS IMPROUED WHEN THE INFLUENCE OF FOUNTDATION AND SOIL IS CONSIDE RED. IT SHOW THAT IT IS CONSERUAITUE NOT TO CONSIDER INFLUENCE OF FOUNDATION AND SOIL. THROUGH ANALYSING THE LOGARITHMIC DECREMENT OF SYSTEM IT IS DEDUCED THAT SYSTEM DAMPING INCREASES BY SOIL. IT IS REASON THAT STABILITY IS IMPROVED. WHEN FOUNDATION MASS DECREASES, THE STABILITY IS IMPROVED TOO. TItESE ISSIGNIEICANT TO ANALYSING SYSTEM CHARACTERISTIC AND DESIGN.
