三次样条函数在海洋水文资料整理中的应用

本文引入三次样条函数插值法,并尝试用于海洋资料处理。根据渤海及北黄海部分海洋站的历史资料进行了试验。用SHARP—PC—1211袖珍计算机进行计算,并将资料处理的结果与传统的过程曲线法订正值作了比较。结果表明,二者之间的误差不大,而样条函数拟合更好。作者认为三次样条函数插值法是可行的,在处理海洋资料时间序列中是有效的。在有温跃层的地方,如何应用,本文也给出了必要的说明。     

Instrumentation and Numerical Analysis of Cylindrical Diaphragm Wall Movement During Deep Excavation at Coastal Area

The lateral deflection of a cylindrical diaphragm wall and the associated ground movement induced by deep excavation are analyzed by performing site instrumentations and numerical analyses in the coastal area of Korea. Wall lateral deflection, rebar stress, and pore water pressure were measured and analyzed in eight directions. Variations of soil properties with the decrease of confining pressure are compared by performing various in situ tests before ad after excavation. To calculate the wall lateral deflection accurately, the effects of small strain nonlinearity, confining pressure, and the hysteresis loading/unloading loop developed during excavation are considered in the proposed numerical analysis. By comparing numerical results with measured ones, the importances of considering small strain nonlinearity and confining pressure reduction in the nonlinear (FEM) are emphasized. Also, the effects of wall stiffness on the performance of cylindrical diaphragm walls are studied for future similar excavation in the coastal area.
