Study Of All-Vertical-Piled Structure In Offshore Deep-Water Wharf

In recent years, with Water Transport's rapidly growing, the development of China's port construction is gradually forwarding to offshore,deep-water,macro-scale and specialization. Though some new structure, such as large flexible breasting dolphin pile and perforated caisson has been applied, the major style is still gravity type caisson berth and ordinary standing pile wharf, it's singler than foreign. So there is very important economic and strategic sense to pay more attention to study the new structure in offshore deep-water wharf.Based on comparing the different styles of deep-water terminal which has been built, the all-vertical-piled structure was recommended in open sea terminal for its merits, such as the reasonable bearing force,quickly constructing,low cost and so on. Combining with one 300,000DWT crude oil terminal project, study on the stability and deformation of main dolphin block when it was composed to all-vertical and rock-socketed piles under the large lateral loading. And research on the single pile that: (1) When the soil was considered, comparing the results of soil-pile contact's nonlinear FEM with linear "m" method, and try to discuss the value's determine of "m" in the situation of pile's large deformation; (2) Search on the influences of pile's stress and deformation under the different rocked depth based on rock-pile contact's nonlinear FEM, while the soil above the rock was not considered.
