储煤场堆载对地基和煤棚桩基影响的离心模型试验研究
Centrifugal model tests on influences of loads of a coal storage yard on foundation and pile-based coal shed
摘要
Abstract
A large coal storage yard is located in the coastal zone,and the soft ground foundation of the coal yard is pre-treated by vacuum pile-loading joint pre-treatment at the early stage of construction.The coal shed of the coal storage yard is designed to be reinforced by the PHC group piles,and the CDM protection piles are set up in front of them.In order to study the influences of long-term large-scale pile loading on the foundation and pile-based coal shed,geotechnical centrifugal model tests are carried out to simulate the two working conditions of cyclic pile unloading and long-term pile loading for 30 years in the coal yard.The test results predict the settlement of the foundation of the coal yard,and further evaluated the safety of the coal yard by analyzing the stress of the pile foundation.关键词
