由于卸荷作用强烈,最大主应力存在明显的应力梯度带,断层对边坡岩体应力场的影响明显。 - This paper also points out clearly that the average stress is the main driving force for migration of the petroleum in the pore stratum , the downhill direction of average stress gradient is the preponderant direction of the migration oil and gas
指出了三维应力场中平均应力是描述油气流体在孔隙地层中运移的主要指标,平均应力梯度减小的方向就是油气运移的优势方向。 - With the consideration of the vertical wave effect of soil and soil - pile interaction , an approximate analytical solution to vertical vibration of pile system with variable impedance in visco - elastic layered soil is developed . a simplified and practical mathematical model for interaction between soil layers is proposed , and its applicability is theoretically investigated . based on this model and by using laplace transforms and the transmit property of impedance function , the analytical expression of the impedance function and solutions of the displacement and velocity response function in frequency domain and in time domain at the pile head are derived
4 、从三维轴对称土模型出发,对考虑桩土耦合作用、土层层间联系以及桩周土竖向应力梯度变化条件下的成层粘弹性土中完整桩及变阻抗桩系统纵向振动问题进行了研究,提出了成层土中变阻抗桩系统纵向振动问题的近似解析解法和桩周土层层间相互作用的简化而实用的数学模型,并利用拉氏变换和阻抗函数的传递性,获得了成层土中任意段变阻抗桩桩顶阻抗函数的解析表达式,以及桩顶速度导纳和时域速度响应解析解和半解析解。 - After the simple analyses with the single phased media theory , a more detailed analyses has been done , based on two phased media theory , on rayleigh wave propagation in saturated soil . the new results show that rayleigh wave will really cause larger shear stress and pore pressure than s wave in shallow layers and thus easily induce sand liquefaction
进一步,基于两相介质理论的有效应力法,研究了rayleigh波在饱水介质中的传播情况,给出了rayleigh方程,分析了饱水介质中产生的应力,并同单相介质模型的结果做了对比,证实了rayleigh波较s波可产生较大的剪应力和法向应力梯度,从而导致液化的论断。 - Compress disk is the very important rotational component in the areoengine . when the compress disk is working , the grads of temperature and stress between the rim and the center of the disk are great . in order to raise the thrust - weight ratio of the disk and reduce oil consumption . the best prospective way is the dual alloys disk used
