Using Biot's 2D elastodynamic theory solves the saturated soil equation. The Fredholm integral equation of the second kind can be built by using the fundamental solution of circular load, the compatibility condition and superposition method. The Fredholm integral equation of the second kind of pile groups can be solved by using numerical method. The numerical solutions of pile groups axial forces, pore pressures under vertical harmonic loading and shear forces, moments and pore pressures under horizontal harmonic loading can be obtained.

The osmotic coefficients and saturated vapor pressures have been calculated at the different temperatures .The experimental values of the osmotic coefficients for the Li_2SO_4-H_2O system were consistent with the values in the references. The results revealed the rules of the changing in osmotic coefficients and saturated vapor pressures with ion strengths and the molality fractions of Li_2B_4O_7 at different temperatures. The isopiestic equilibrium molalities were correlated by using the modified and the extended Zdanovskii rules for non-ideal mixtures, and obey well the Zdanovskii rules.

The test results show the principle of variation of pressures on culverts beneath high fill is similar, it is that, even if the embankment is filled up to a higher height, the earth pressures can still partly transfer to the top of culvert, as a result the pressures on the culvert increase nonlinearly with the variation of height of fill and further the pressures are obviously lower than theoretical value by σ=γH.

模型试验和数值模拟计算结果表明，当填土达到一定高度后，高填方涵洞上方将产生明显的拱效应，但由于涵洞填土为破碎的岩土，其拱效应与岩石中开挖洞室上方的拱效应不同，高填方涵洞上方填土产生的"土拱"效应具有不稳定的特点，表现为随着填土高度的增加仍有部分土压力传递到涵洞上，涵顶土压力随填土高度成非线性增加。

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.
