Compared with soil destroyed pattern of vertical force and its controlled factor of bearing capacity,it is concluded that pile capacity and its tip resistence have some difference when soil with the same physical mecanic property is used as natural foundation and pile tip resistent layer.Whereas the middle weathering rod Stratum hasn't this property,that is to say it has the same bearing capacity and pile tip resistence.

文摘：通过竖向荷载下土体的破坏模式及其承载能力控制因素的比较，论述了物理力学性能相同的土层作为浅基础的天然地基与桩端持力层时，承载力值与桩端阻力值应存在一定的差异；而中风化程度的同一岩层作为天然地基与桩端持力层时，不具有这方面的差异性，承载力值与桩端阻力值应该相等。

The dynamic response characteristics and variation of bridge structure, pile foundation and soil layer are analyzed, while the peak acceleration of Rayleigh wave is progressively increasing.

采用逐级增加动力荷载的方法，分析了在Rayleigh波加速度峰值逐级增加后，桥梁结构、桩以及土层的动力反应特点和变化规律。

Furthermore, authors statistic actual impacting times in the local by various types of hammer when the pile drives into the different depth of the bearing stratum, it may offer the reference for the similar engineering to choose the hammer in the future.

因此，如何对该类型的桩进行合理沉桩分析，是桩基施工中急待解决的问题。 2沉桩阻力在沉桩施工的过程中，桩锤的冲击力应大于土层的沉桩阻力，桩才能顺利下沉。

During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.

在宁波市北渡－雅戈尔原水D1800mm钢管复线工程顶管施工中，出现主顶动力站顶力异常增大的现象，影响继续顶进施工，文章针对这一情况进行分析研究，通过理论顶力曲线与实际顶力曲线以及工具管所经轨迹与管道在土层中静止时的形态图的分析比较，得出主顶动力站顶力过大是因为在纠偏过程中纠偏角度过大，使管道在短距离内过度弯曲引起的。

For the understanding of the kinetic variation and distribution of Cl in tobacco area soil of upland yellow-red earth in South Anhui ,soil samples were collected in 4 times of tobacco growth :early winter of 2002,before transplanting in next year, beginning midway, and leaf collecting .

通过对皖南旱地黄红壤烟区进行施Cl处理，施Cl后分别在初冬、次年移栽前、采烤开始、采烤中期、采烤结束后，分五次分别挖土壤剖面取土样；每次剖面层分别取0-20cm、20-40cm、40-60cm、60-80cm的土层土样，同一层同时取4-5点混匀作为一个样品，分析土壤Cl的动态变化。

So from the aspects of economical and social benefit, it has a lot of advantages. On the other hand CFG pile with long screwy drill pipe inner pump pressure is low noisy and without muddy water pollution; The process of drilling will not lead to vibration and has the capacity to penetrate hard rock layer; Also the construction is of high efficiency.

并且长螺旋钻管内泵压成桩工艺具有低噪音，无泥浆污染；成孔制桩时不产生振动；成孔穿透能力强，可穿透硬土层，诸如沙层、圆砾层和粒径不大于60mm的卵石层；施工效率高等优点，所以该技术在全国推广后，得到了广泛的应用，目前已成为应用较为普遍的地基处理技术。

Planted vegetation, especially more than 20 years old planted trees and planted grasses consumed much more soil water than vegetation in natural restoration, and the soil water content in 200-500cm soil layers was almost near to wilting point.

相比之下，人工植被消耗大量的深层土壤水分，特别是20年龄以上的人工林地及人工草地，其200~500cm土层的土壤含水量几乎接近凋萎湿度。

Aftercomparison, the reinforced concrete sheet pile wall in combination with anchor rodstructure was adopted for the levees.

经方案比较，堤岸采用了钢筋混凝土板桩结合土层锚杆锚固的结构型式。

Two groups of field tests on original soil and the soil among piles ,three groups of field tests on single pile ,one-pile and three-pile composite foundation have been conducted and the results of the bearing capacity ,as well as the elastic modula of each pile and composite foundation are obtained.It can be seen that soft earth reinforced by cement-soil piles seem to have better appearance in bearing and deforming than original one.

通过桩间土、原状土各两组，单桩，单桩与多桩复合地基各三组的现场静载荷对比试验，获得了各自的容许承载力值，根据P-S曲线计算出的变形模量结果表明，地基经过粉喷处理后，地基力学性质和变形特性得到明显改善，土层的强度和变形模量明显提高。

The experiment of soil moisture conservation in summer fallow land in the years of1983～1984 indicated that the method to mulch.

1983年和1984年进行的夏闲地保墒方法试验表明，采用麦糠或麦草覆盖的方法可以在0～2m土层多保蓄土壤水分54～64mm。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
