The results showed that available nutrient content have little difference in 0-10cm and 20-40cm soil of grassplot, but available nutrient content in 0-20cm soil higher than in 20-40cm soil of other land uses patterns.

结果表明：草地的在两个土层速效养分含量差别不大，而其他土地利用模式0-20cm土层的速效养分含量均高于20-40cm土层。

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

结果表明：研究区各重建森林前一个月的土壤含水量对当月整个土壤剖面(0~40 cm)平均土壤含水量和当月20~40 cm土层土壤含水量具有较强影响，对当月0~10 cm土层土壤含水量的影响较小；研究区各重建森林20~40 cm土层土壤含水量主要受当月降水量的影响，0~10 cm土层土壤含水量主要受当月蒸发量的影响；在4种森林重建模式中，枫香纯林当月降水量与当月土壤含水量的相关系数最大，混交林模式土壤含水量的自相关系数大于纯林模式。

By means of the orthogonal expansion technique, the coupling system solutions are finally obtained. Then the dynamic model of saturated soil layer caused by pile longitudinal vibration is founded. Incorporated wave propagations into saturated soil layer, the characteristics of soil resistance factor and the mechanism of the radial damping are analyzed, as well as distributions of shear stress and pore pressure in saturated soil caused by pile vibration.

然后利用上述解析解分析了饱和土层复阻抗，并从饱和土波动理论出发，建立了桩纵向振动引起的饱和土层振动模式，剖析了辐射阻尼产生机理，研究了桩纵向振动引起的饱和土层中剪应力及孔隙水压力分布。

For the deep soft soil, piles usually can t penetrate the entire soft soillayer, and there is thick soft soil subjacent bed under the piles.

由于沿海地区的软土层较厚，基桩往往未穿透整个软弱土层，桩端下存在较厚的饱和软土层。

Use instead and fasten and dig the bit to remove the hole and bottom eluvial soil after 5m (if the rock meeting high hardness while the base rock creeps into, can is it inlay rock bit get into to designing requirement hole dark by fastenning and digging and fighting the clear hole and then to use instead), in order to improve the strength of bearing the weight of of one , put the reinforcing bar cage finally , build the concrete.

本工艺基本上适应于各种土层，如软弱土层、松散杂填土、粉土、砂土、粒径不大（10cm以下）的碎石土和圆砾及其它塑性不大、粘粒较少的粘土，尤其适用于软塑、流塑、孔隙比大、高压缩性、抗剪强度小等特性的淤泥质土及因地下水丰富造成泥浆护壁困难的土层。

Temporal and spatialcorrelation of Soil moisture under vertical direction was affected by some factor such asmeteorology, land use and fertilization measures. All siol moisture in different layers hastemporal and spatial correlation when soil moisture fluctuates of surface layer becausestability, but influence ability of each factor is not the same. For example, meteorologyhas most strong impact on temporal and spatial correlation of soil water content.

在气象条件较稳定的情况下，不同植被覆盖和不同施肥措施下各土层含水量之间都具有较强的时空相关性，随着气象条件波动加剧，各土层土壤含水量的时间相关性和空间相关性都降低；植被因素相对气象条件对各土层含水量的时间自相关性影响较小，而对各土层土壤含水量之间的空间相关性影响较大，裸地和农田各土层土壤含水量之间的空间相关性相对林地和草地较弱；不同的施肥水平都削弱了土壤各土层含水量的时空相关性。

The 0-40cm soil layer soil mean value looked that mixes by the interlacing broadcasts the lawn soil ulmin, the alkaline hydrolysis nitrogen content to be highest; The fast-acting phosphorus, the fast-acting potassium are highest by the unicast awnless brome lawn content; The colleague mixes broadcasts lawn pH to be biggest.

不同播种方式下土壤有机质、碱解氮、速效磷含量在0-40cm各土层内呈现随着土层深度的增加而降低的趋势，均以0-10 cm土层土壤含量为最大；同行混播和隔行混播草地速效钾呈现降低的变化趋势，单播无芒雀麦草地则呈现先降后增再降的变化趋势，以0-10 cm和20-30 cm土层土壤含量为最大，均为80，并与其它土层间达到极显著差异；pH则呈现出增加趋势。0-40cm土层土壤平均值来看以隔行混播草地土壤有机质、碱解氮含量最高；速效磷、速效钾以单播无芒雀麦草地含量最高；同行混播草地pH最大。
