I graduated from the former Hsiang Ya Medical College (a Yale-affdiated medical school in China before Liberation in 1949, and the predecessor of today’s Hunan Medical University) in 1952. My aspiration to be a clinical doctor was strongly influenced by my father Sophie (his pen name) whereas my devotion for all my life to neuro-anatomy resulted from the interaction between the mandatory system of work assignment by the State and my personal selfdevelopment. In the year of my graduation, the Ministry of Public Health under the National Military Commission was in need of a human anatomy lecturer and asked its civil counterpart to select a nominee for the vacancy. At the time, Ihad chosen basic medical research as my career and anatomy was definitely not one of my options, nor was any of my classmates in favor of it.

三峡库区周期性水位升降引起的消落带岩体劣化对典型危岩岸坡稳定性具有重大影响。基于野外调研及地勘资料,采用通用离散单元法程序(universal distinct element code,简称UDEC)研究了消落带劣化区形态对近水平层状高陡危岩岸坡的稳定...三峡库区周期性水位升降引起的消落带岩体劣化对典型危岩岸坡稳定性具有重大影响。基于野外调研及地勘资料,采用通用离散单元法程序(universal distinct element code,简称UDEC)研究了消落带劣化区形态对近水平层状高陡危岩岸坡的稳定性影响。研究表明:目前三峡库区巫山段的近水平层状危岩岸坡消落带岩体劣化严重,在不同消落带劣化区存在紧密层状、松散碎裂状、溶蚀凹腔状、含挤压碎裂带等典型消落带劣化区形态;含有第1种消落带劣化区形态的危岩岸坡稳定性较好,危岩体位移较小,失稳模式为滑移破坏;含有第2种消落带劣化区形态的危岩岸坡危岩体先向坡内偏移,其后随着消落带岩体支撑强度弱化向坡外倾倒破坏;含有第3种消落带劣化区形态的危岩岸坡危岩体向坡外位移较大,失稳模式为倾倒破坏;含有第4种消落带劣化区形态的危岩岸坡稳定性主要受挤压破碎带的力学性质控制,易产生沿破碎带切割面的旋转滑移破坏;通过对以上4种劣化区形态的危岩岸坡增加防治加固措施,危岩体的变形位移得到了不同程度的有效控制。展开更多
