主要成果
| 科研成果: (1)开展了复杂地质条件下以高坝、深埋地下洞室为特点的水利枢纽渗控系统优化分析的数值方法研究工作,为国家重大水利水电工程建设服务。先后负责或为主完成了双江口水电站、溪洛渡水电站、猴子岩水电站、锦屏二级、冶勒水电站、糯扎渡水电站、泰安抽水蓄能电站、白鹤滩水电站、王庆坨水库防渗技术等一批大型水电工程的渗流分析及渗控系统优化课题研究。 (2)建立了多孔裂隙岩体介质的流–固–热–化学四场全耦合数学模型并实现了数值求解,利用多个已知解析解和数值解的算例来证明了耦合模型及求解方法的正确性。 (3)引入图像数字化技术来客观地反映裂隙岩石的非均质性结构分布,能较真实客观地反映岩体的主干裂隙、次裂隙及裂隙化区域和较完整岩块的分布,该方法比统计学随机抽样方法有明显的优点。然后将其和数值方法相结合,建立起基于图像数字化的裂隙岩体多场耦合分析方法。该方法比统计抽样方法有明显的优点,其结果更能反映真实的物理现象。 (4)提出了在渗流-应力-水化学溶解耦合作用下岩石单裂隙渗流特性演化及优势渗透通道的形成机理,并建立了渗流-应力-化学耦合作用下单裂隙渗透特性数值分析模型。研究认为:在裂隙面形态改变过程中,有两个对裂隙面形态变化产生重要影响的作用:(1)压力溶解作用,压应力和水化学使接触面(岩桥)加速溶解,从而促使裂隙面闭合。(2)孔隙壁面的表面化学溶解,使局部孔隙增大,促使裂隙优势渗流通道形成。这两种作用先后对裂隙面产生控制性影响,从而使裂隙渗透特性发生不同的变化。 主要论文论著: 1.Liu J, Sheng J C, Polak A, Elsworth D, Yasuhara H and Grader A.
