The increased amount of non--exchangeable NH4^＋-N during the incubation indicated as the following tendency, namely, Eum-Orthic Anthrosols 〉 Los - Orthic Entisols 〉 Hap-Ustic Isohumisols 〉 Ust-Sandiic Entisols. Organic material influenced significantly the increased amount of non-exchangeable NH4^＋-N （P was 0.0002, 0.0004 and 0.0003 when incubated at 20 d, 50 d and 60 d, respectively）. NH4^＋-N increased remarkably when Stlpa bungeana and Medicago sativa were added compared with no addition. The contents of non-exchangeable NH4^＋-N increased significantly when added （NH4）2SO4 compared without addition at 20 d, 40 d and 60d of incubation and P was 0.0037, 0.0033 and 0.0027, respectively. It was the result that the NH4^＋-N from （NH4）2 SO4 was fixed within the soil. The increased amount of non-exchangeable NH4^＋-N increased significantly for different soils, on which different vegetation types grew before the collection of soil samples, when incubated at 20 d （P=0.0434）, but not significantly at 40 d and 60d （P=0.7378 and 0.5375）. The increased amount of non-exchangeable NH4^＋-N in the soil, on which crop straw and nitrogen fertilizer had been incorporated for a long-term period, was larger than that of no addition, but it was not significantly different among these two fertilization models. Soil clay, total N and organic matter were positively correlated remarkably with the contents of non-exchangeable NH4^＋-N, the increased amount of non-exchangeable NH4^＋-N had no correlation with soil clay, whereas it had significantly positive correlation with total N and organic matter.

Better numerical prediction of the distributions of shear forces and bend moment within the pile group has also been obtained with the consideration of many stochastic parameters such as the soil properties of sea warf, seismic properties, etc. And then we analyze the dynamic nonlinear seismic pile-soil interaction in sea warf as an example to apply the software of ANSYS to the assessment of the dynamic interaction of soil-structure in the harsh situation of random earthquake. And then we denoted that the soil-pile interaction is too difficult to be expressed in equations because the non-linear interaction between soil and pile.

5桩基由于其本身的优点得以在海洋码头结构中大量的运用，但是海洋码头结构在海洋环境下受多方面的影响，土与桩体的相互作用关系很难清楚的表达，由于影响因素的多样性及复杂性，以及它们与桩基性状之间的非线性和非确定关系，使得关于桩基性状的各种理论解答还不能采用简便的表达式以反映其复杂多变的机理，尤其是难于反映施工及环境因素对桩基性状的影响，而且如何发挥桩基的技术经济效益和如何合理的确定桩的极限承载力，也是一个技术难度很大的问题。
