Through analyzing the data of a series of shaking table tests of dynamic soil - structure interaction ( ssi ) system with soft to hard soils , the transfer of earthquake wave in various ground soils is in vestigated 摘要通过对地基土质从软到硬的三个阶段结构地基动力相互作用体系振动台模型试验所取得数据的对比分析，讨论了不同土性地基对地震波传递的影响。
The right sensitiveness is relevant to the mean value . whether mean value of soil parameter is obviously heavy , comparatively speaking , sensitiveness obviously increases of another soil parameter to dependability index as a certain soil _ c 、 _对的敏感性同c ，均值相对大小有关；当某一土性参数均量明显大时，另一土性参数变量的对可靠性指标的敏感性明显增大。
Furthermore , it was shown that load - displacement of pile groups and load distribution on pile top were affected by properties of soil and stiffness ratio of piles to soil , and by length , diameter , spacing , and number of piles 在此基础上，分析了刚性承台条件下超大群桩基础的荷载位移曲线变化规律以及桩顶荷载分布规律受桩土刚度比、桩长、桩径、桩距、桩数、土性等因素的影响规律。
As for actual embankments , the hydraulic head , cross section shapes , properties of filled soil , geological conditions and so on all vary greatly , it ' s hard to define precisely the distribution of seepage field and take effective seepage prevention measures 因实际工程中堤防的作用水头、堤身断面、填土性质、地质条件等均千变万化,导致难以全面而准确地分析其渗流场分布并采取有效的防渗措施。
Lt covers 337 , 000 km ~ 2 with the heature of flowing in recent years , the focus area of oil exploit is moved to west chira accordingly , the engineering characteristics of desert sand are drawing more and more ettenti of civil engineer 塔克拉玛干沙漠是我国面积最大的沙漠（ 33 . 7万平方公里） ，也是世界上第二大流动性沙漠。近年来，随着石油开发重点的西移，沙漠砂的岩土性质引起了广大工程技术人员的注意。
According to mass of the testing data of clay silt and silty clay in beijing and based on mathematical statistic theory , this paper analyzes statistically the physical mechanics indexes , discusses the distribution features of clay indexes and their differentiation 摘要根据北京地区大量的粉质粘土、粘质粉土土工实验资料，基于数理统计理论，对其物理力学指标进行了统计分析，探讨了各土性指标的规律分布特征，分析指标的变异性。
It has been shown that no matter what kind of assumption is adopted for soil in a consolidation analysis , nonlinear or non - homogeneous , the result obtained differs greatly from terzaghi ' s theory . and the coefficient of consolidation is not the only parameter of soil that affects the one - dimensional consolidation behavior 本文的工作表明：在固结分析中对土性无论是采用非线性假定还是采用非均质假定，其结果都与传统的太沙基固结理论有很大的差别。
( 4 ) in the situation mat other variables keep unchanged , the sensitiveness degrees of and to are different , the sensitiveness of c to should obviously be stronger than to . ( 5 ) shows a tendency to drop when f increases . - f is different under different mean value ( 4 )在其它变量保持不变的情况下，粘土边坡的可靠性指标受土性参数c ，均值的影响程度是不一样的，对_ c的敏感性公路土质边坡稳定可靠性分析及综合防护体系研究明显要强于声， 。
Second , based on the parameter study of pile foundations , the corresponding relationship between the soil property parameters needed in the finite element method and the engineering parameters of soil in dynamic machine foundation design code ( for short of dynamic code ) is presented in this paper 在桩基参数研究的基础上，本文将有限元计算中需要的土的性质参数与《动力机器基础设计规范》 (简称《动规》 )中的土性工程参数进行了研究，得到了二者之间的关系。
The formulas for computing mean and deviation of the average consolidation degree of double - layered soil are derived as vertical coefficient of consolidation submitting to gamma distribution . with these formulas , the influence of geotechnical auto - correlation distance to the probability characteristics of consolidation degree is studied . it shows that along with the rising of auto - correlation distance , the sensitivity of probability characteristics of consolidation degree to auto - correlation distance is falling 当竖向固结系数为gamma分布时，推导了双层地基平均固结度均值和方差的计算公式：利用该公式分析了土性自相关距离对平均固结度概率特性的影响，结果显示，自相关距离越大，平均固结度的概率特性值对自相关距离越不敏感。
