Preliminary Study About Foundation Vertical Stress Distribution on Diversion Culvert of the Yellow River Sluice
摘要
Abstract
Water diversion culvert of the Yellow River sluice often uses frame model in the stress analysis,and vertical stressσy distribution of its foundation has a direct impact on the ground reaction force forms. To solve this problem,it investigated and studied 31 sluices in Henan section of the Yellow River,including the structure of the form (including culverts longitudinal section and cross section characteristics, strength of concrete,wire stiffness,and so on),culverts upper filling height,soil and other aspects of basic research,induced and analyzed the characteristics of diversion culvert based on the design and completion drawing,summarized the main features of the culvert,and as a ba-sis for typical culverts,used numerical simulation method to study the distribution of vertical stressσy research foundation. The results show that it can get its laws in line with 6 polynomial conclusion and give the proposal about stress analysis culvert by the elastic foundation bound-ary.关键词
