Research On Solidified Theory And Detection Method Of Dynamic Consolidation Rely On An Oil Depot Foundation Reinforcement Engineering In Zhoushan

Dynamic consolidation method is an efficient and economic method of foundation treatment, which has a great advantage in large area foundation treatment, and it has already been adopted in plenty of celebrated engineering. Although the research on theory of dynamic consolidation in foundation stabilization has made great achievements, evaluation methodology in this field still rely on experience and qualitative judgments, especially reinforcing effect of gravely soil filling Foundation.The author do some research on the principle, construction design and detection method of dynamic consolidation, combined with an example of an oil depot foundation reinforcement engineering in Zhoushan.This article introduces mechanisms of dynamic consolidation of saturated soil and unsaturated soil mechanics in the soils in micro and macro aspects, discusses the tamping energy transmittal mode in soil, explore the design procedure for calculating the depth of dynamic consolidation and the factors that influence the effect of dynamic compaction. Through analysis of pore water pressure and consolidation deformation monitoring which acquired by the field investigation to determine the optimal parameters of dynamic compaction construction. And evaluation of foundation reinforcement effect based on the result out of after ramming load testing, dynamic penetration testing and Rayleigh wave testing. Establish the correlation between the parameters by the comparison of three experimental results. Analyzing the work site inspection common problem, and summarizes the applicable detection system of gravel soil filling foundation combined with engineering experience.
