In the second part, by using uniform design and orthogonal design methods, some groups of mix test of foam lightweight with different component are conducted, the test data is analyzed by neural networks model and regression model, and optimum mix proportion is obtained. Orthogonal design for mix material considering density factor is presented, as well as uniform design for mix material adapting to different density. The mechanic characteristics of foam lightweight material and engineering characteristics differing from general material under an allround press are founded. Through the analysis of asymmetry settlement for Doulong sluice and the comparison of correct deflection scheme, the foam lightweight material shows some advantages in the load reduction.

This paper examines the soil characteristic and liquefaction degree of hard shell seams at the subaqueous delta of the Yellow River. Four typical areas were chosen for measuring, testing and studying. The hard shell seam strength was measured by in-situ Proctor penetrometer. Undisturbed soil sample of 1 m long was excavated for laboratory soil property test. Sledge hammers were dropped down freely to hit the load board to simulate the wave force acted on the hard shell seam. The excess pore pressure and strength variation were observed. The liquefaction depth of the hard shell seams at four study areas under different wave storms were calculated by theory.
