Abstract:

On account of the north anchorage of Maanshan Yangtze River bridge, the drawdown of caisson foundation may bring about new seepage field of the ground, which make soil consolidate. This paper build two-dimensional plane strain finite-element models of open caisson and the Yangtze River levee, which aim to analyze the effect on the Yangtze River levee by drawdown of the open caisson foundation. Through the seepage analysis of the open caisson foundation and the stability analysis of the slope, this paper obtain the settlement and coefficients of stability against sliding of the Yangtze River levee.

Abstract: As a new type of deep water offshore foundation, suction caisson is widely used to offshore structures. However, the current methods of evaluation and design cannot meet the increasing requirement of engineering practice. In this dissertation, the studies are emphasized on finite element method for analyzing the suction caisson bearing capacity behavior and the failure mechanism under the vertical load. Based on studying the vertical bearing behavior of caissons with different ratio of length to diameter L / D, it shown that as L / D increases, the vertical bearing capacity growth slowed.
