竖向

Based on the sliding response theory of the free-standing equipment, the differential equation of motion of the free-standing equipment under seismic excitations is presented. The equation is solved by Runge-Kutta algorithm, therefore the absolute acceleration, relative velocity and relative displacement of the equipment can be obtained. The sequential coulomb friction model is applied to the analysis.

摘 要：将碾压混凝土坝视为具有各向异性弹性特性的均质体，通过在垂直于层面的竖向和平行于层面的横向采用不同弹模来考虑层面对坝体应力影响；同时考虑了坝基弹性的变化对坝体应力影响。

In addition, the vertical stress on every anchor block is identical the same. That is to say , when the external force is balanced, because the upper part of the space truss distribute it on all the anchor block, every one sufficiency display the ability of anti-pulling out.

通过分析还发现，各圈地锚受到的竖向应力基本相同，就是说在平衡外力的时候，每个地锚都充分发挥了抗拔能力，这是因为上部的空间桁架结构很好的将力分配到了每个地锚上。

The blasting test demonstrates that the horizontal stress wave contributes more to water drainage than vertical stress wave, reducing water drainage distance is favorable to squeezing water and consolidation of soil, the blasting powder amount influences lest result greatly.

爆炸试验表明，水平向应力波对土体排水的贡献大于竖向应力波，缩短排水距离有利于土体的排水固结，炸药用量对试验有很大影响。

When the seismic intensity in vertical direction takes a high ratio,it is hard to accurately estimate the maximum displacement demands on structure by the traditional Pushover method.

通过对其进行改进，提出首先对结构按一定方式施加竖向地震引起的惯性力，随后进行结构水平向的多模态推覆分析，并按SRSS方法计算其最大位移需求。

The results show that, the chloride concentrations and diffusion coefficients are both a one-humped function of elevations (can also be the time scale of seawater infiltration), they increase with the increase of elevation until they get to the peak value, and then decrease with the increase of elevation; an evident relationship is being between the surface chloride concentrations and the wave forces acted on the concrete surface, while there is no much difference among the diffusion coefficients; the diffusion coefficients get to bigger as the depth from the concrete surface increase in the influence of the capillary structures evolution and chloride concentration, but this tendency of change was alleviated with the increase of depth.

研究结果表明：氯离子侵蚀混凝土设施的竖向分布规律为氯离子浓度、扩散系数与标高之间同为单峰函数分布，先随高程变大而变大，达到峰值后，随高程变大而减小；氯离子侵蚀混凝土设施的环向分布规律为混凝土构件表面氯离子浓度、氯离子通量与波浪力之间有明显的对应关系，波浪力越大，则表面氯离子浓度和氯离子通量越高，而扩散系数在各方位角差别不明显；由于混凝土长期服役过程中内部毛细孔隙结构演化以及氯离子浓度的影响，氯离子扩散系数随混凝土深度变大而变大，但这种变化趋势随深度逐渐趋缓。
