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.

The war was a complete subversion of the war in the past to attack ground-based understanding of the concept; the Federal Republic of Yugoslavia in the war, the US-led NATO forces did not put in ground troops, the use of the Federal Republic of Yugoslavia Precision guided weapons of indiscriminate bombing, eventually forcing the Federal Republic of Yugoslavia to yield more ground attack proved that the traditional mode of war will soon be empty by the Navy-led joint operations by replacement of the three services, ground troops in modern warfare status, others Gradually given way to decline in the Air Force and Navy.

这次战争彻底颠覆了人们的对以往战争的以地面进攻为主的认识观念;在对南联盟的战争中,以美国为首的北约部队,在未投入地面部队的情况下,对南联盟采用高精度的制导武器狂轰滥炸,最终也迫使南联盟屈服,更证明了地面进攻的传统战争模式即将被以空海军为主导的三军联合作战所替代,地面部队在现代战争中的地位,己逐步下降让位于海空军。

Therefore,a series studies of ice-pier vibration are performed from different aspects in this paper.The main work of this his thesis is summarized as follows:(1) Ice response spectra is proposed based on the idea of a seismic response spectra analysis of str .. uctures.Firstly,ice response spectra on the basis of power spectra density function is established;Secondly,based on the assumption of quadratic parabolic interpolation method,the nonlinear interpolation analysis method of ice response spectra is studied from both theoretical and practical points of view,and the successive computation formulas including ice displacement,velocity and acceleration response spectrum are deduced by Duhamel integral.Furthermore,to analyze the effectivity and applicability of the method, the real temporal curves of ice pressure are used to be studied.The results show that the presented method is more convenient and accurate to study the structural response induced by ice force,also it can be effectively applied in the design of ice resistance.
