随围压的增大，冻土的强度增加，但随着围压的进一步增大，强度出现降低的趋势，也就是说围压的增大可以抑制冻土的膨胀软化效应，也可以诱导冻土的膨胀软化现象。

Vesic's solutions to cavity expansion that include cylindrical cavity expansion and spherical cavity expansion are introduced. Then cylindrical cavity expansion theory is applied to study compaction effect of pile driving in saturated soil. Based on the results of conventional triaxial tests, a trilinear curve model is used to simulate stress-strain curve of strain-softening materials. Meanwhile, trilinear curves are also used to simulate curves of volumetric strain, minor principal strain and major principal strain. By using elasto-plastic theory, analytical solutions to cylindrical cavity expansion in strain-softening soil are presented. According to the mechanism of statically pressed pile driving, compaction effect of pile tip can be viewed as hemispheric cavity expansion. Therefore spherical cavity expansion theory is applied to obtain the solutions to stress, strain, displacement fields and final pressure. Resistance force of pile tip is calculated to estimate static pressure.

The results show that the mechanical properties of this PMMA depend strongly on the testing temperature. The Young's modulus and flow stress were found to decrease with increasing temperature at low strain rate. At the strain rate of 10^(-1) 1/s, strain soften was observed under all experiment temperatures. At high strain rate, with the temperature increase, the flow stress deceases remarkably while the failure strain increases, and the strain softening was also observed at the temperature above 333K.

试验结果表明：在准静态载荷下，随着温度的升高，材料的弹性模量和流动应力减小，在应变率为10^(-1) 1/s时表现出明显的应变软化行为；在高应变率(550 1/s)下，随着温度的升高，材料的流动应力逐渐减小而破坏应变增大，当温度超过333K时也有应变软化现象发生；在相同温度下，随着应变率的升高，材料的流动应力增大，但破坏应变减小。

The capacity of single pile will enhance when the length and diameter of pile increases, but effect of pile diameter is more obvious. While pile diameter increases 20、40 and 60 percents, the capacity of pile will enhance 20.4、53.7 and 78.1 percents. And with the effect of mud-cake, the capacity of single bored pile will fall down nearly 20 percents, and pile-side resistance will also reduce 15 — 35 percents. In the centrifuge tests, when the relative displacement between pile and soil was 45 —85mm, which is much more than the criterions, the pile-side resistance will become most. Meanwhile the intenerated value of utmost resistance is close to the resistance in situ. In the pile group tests, the capacity of pile group , which the space among piles increases from 2D to 3D、 4D and 5D , will enhance 6.1、9.6、18 percents .

当桩径增加20%、40%、60%时，桩承载力分别增长了20.4%、53.7%和78.1%；在考虑泥皮效应后单桩侧摩阻力减小15～35%，极限承载力减小18%～24%，且减小率随桩径的增加而变小；试验中桩身侧阻软化值与原型桩实测侧阻软化值接近，且极限侧阻所对应的桩土相对位移试验要比规范值大得多，约为45～85mm；同时群桩极限承载力随桩距的增大而增加，其中桩距为3D、4D、5D的群桩承载力分别比间距为2D的群桩高6.1%、9.6%和18%；其承载力效应系数η接近或大于1，并随着桩间距的增大而不断提高；群桩侧摩阻力沿深度的分布与单桩略有不同，即桩身上部由于承台的作用，侧阻削弱，但桩身中部侧阻具有增加的趋势。

A cusp catastrophe model is presented to describe the behavior of sliding along one deep incompetent structural plane of a gravity dam foundation, and the sufficient conditions leading to instability are discussed. It is found that the instability of sliding relies mainly on the stiffness ratio k, the homogeneity index of the medium m and the geometry-mechanic parameter ξ and that the reliability of the traditional limit analysis method is deficient.
