摘要
采用OptumG2有限元软件,分析不同水位埋深对地基承载力和浅基础沉降的影响.研究发现,随着水位的降低,黏聚力和内摩擦角愈大,地基极限承载力愈大,基础沉降愈小.水位埋深较小时黏聚力和内摩擦角对地基承载力和基础沉降的影响较大,随着水位埋深的增大,影响逐渐减小;对于同一水位埋深,黏聚力和内摩擦角愈大,其对地基承载力和基础沉降的影响愈小;相对于内摩擦角而言,黏聚力对地基承载力和基础沉降的影响大.
The influence of different underground water on shallow foundation is investigated. The result proves that with the lower water level, the ultimate bearing capacity of foundation is bigger and the settlement is smaller with the cohesion and internal friction angle increasing. When the water level is low, the cohesion force and internal friction angle of foundation greatly influence the bearing capacity and foundation settlement. However, with the water level increasing, the influence is smaller. As the same water level, the more cohesion and internal friction angle, the smaller effect of bearing capacity and foundation settlement . Relative to the friction angle, the cohesion forcegreatly influence the bearing capacity and foundation settlement.
