摘要
依托水利部公益性行业科研专项经费项目,对胶凝砂砾石材料进行系统而全面的试验研究.掌握胶凝砂砾石材料力学特性,建立材料性能指标体系;寻求适合胶凝砂砾石材料性能的合理的本构模型;研究坝体应力、应变实际分布状态,确定坝体基本剖面设计原则和控制标准;并对胶凝砂砾石材料在温度变化及冻融影响下的耐久性进行深入研究.促进这一具有明显优越性新坝型的快速发展.
Relying on MWR nonprofit industry research and special project funding, systematic and comprehensive experimental study on cement-sand-gravel （CSG） materials has been conducted to master the mechanical properties of CSG materials, build the material performance index system, seek reasonable constitutive models for CSG properties, study the actual distribution of stress and strain state of the dam, determine the basic profile design principles and control standards, and study the durability under the conditions of changes in temperature and freeze-thaw. Accordingly, the achievements would promote this new type of dam with obvious advantages developing rapidly.
