2 遥感和数值模拟

Doug Stead教授接受的高等教育全部在英国，学士学位在埃克塞特大学(University of Exeter)，硕士学位在利兹大学(University of Leeds), 博士学位在诺丁汉大学(University of Nottingham),上个世纪90年代，他从英国移居到加拿大，在Burnaby的西门菲莎大学SFU(Simon Fraser University)工作。Dr. Stead的专业为工程地质和岩石力学，对边坡稳定性及其破坏机理进行了广泛研究。Dr. Stead为中国培养了至少4位博士研究生。“利用遥感和数值模拟相结合的方式评价边坡坡坏机制”是Dr. Stead近年来的其中一个研究方向。这项研究工作的具体内容体现在他的部分学生的学位论文，主要包括:
