This thesis points out three conditions of favorable soil-returning volume,and gets the critical water-content coefficient of bed-irrigating sowing, andthinks that water volume, soil—returning in volume and initial soil water contentcoefficient affects differently the course and the result of infiltration, and revealsthe laws of variations of soil moisture content, and shows the different effect onsoil - wedded states of water volume, depth of seed ditch, soil apparent density,soil-covering depth,initial soil moisture content, width of seed ditch and soil-wedding states, and suggests that the soil-wedding state watering after sevendays is use to evaluate the quality of bed-watering seeding.

结果表明灌水量、种沟宽度、回土量和土壤初始含水率对入渗过程和入渗结果存在不同影响；揭示了坐水播种土壤含水率在种沟断面上的变化及其随时间的变化规律，模拟结果还表明了灌水量、种沟深度、土壤容重、覆土厚度、土壤初始含水率、种沟宽度、回土量对土壤湿润状况的影响及确定适宜回土量的三个条件。

Firstly, a computational formula of RS which used widely in pipelines design is introduced. Secondly, a correction formula is deduced based on Spangler model. Thirdly, a model of buried pipelines is analyzed with finite element program. After compared with different results, it is found that the result from the correction formula matches with the result of FE better than that of the design code.

以现行的管道结构设计规范为例介绍了目前管道工程设计中常用的管土相对刚度计算公式，在Spangler管道土压力模型基础上推导了计算埋地管道管土相对刚度的修正公式，并采用有限元模型分析了上埋式管道的管土相互作用机理。

In the subtropical cropland soil, decompositionrate of organic carbon in paddy soil due to ground water is periodical water-logginghuangnitian＞gley huangnitian＞submerged huangnitian; decomposition rate of organiccarbon in dry land soil is vegetable soil in Nanjing＞red soil in Yujiang＞fluvo-aquic soilinYujiang.

亚热带农田土壤中，水稻土受地下水升降的影响，有机碳分解速率顺序：潴育黄泥田＞潜育黄泥田＞淹育黄泥田；旱地土壤有机碳分解速率曲线依次为：南京菜园土＞余江红壤＞余江潮土。

The fixed-NH+4 capacity of all natural layers in lou soil was determined in this thesis,they were 482.2±10.4,1134.9±4.0 and 553.0±11.3 mg N／kg soil in overburden layer,claying horizen and loess parent material horizen respectively.
