Liu Baochen, member of  Chinese Academy of Engineering

Liu Baochen, male, was born in Kaiyuan County, Liaoning Province in 1932. He is expert of geotechnical engineering, founder of the Chinese theory of random media and pioneer of its applications, who is currently the professor and PhD supervisor at School Civil Engineering of Central South University. Early in 1962, he obtained doctoral degree in technical sciences for his outstanding achievement in the Cracow Mining and Metallurgical College (Poland). Former research director and vice president of Changsha Research Institute of Mining and Metallurgy (CRIMM), adjunct professor of Central South University, Northeastern University and China University of Mining, vice chairman of Rock Mechanics and Engineering Society of China, and so on. In 1994 was elected as foreign member of the Polish Academy of Sciences, in 1997 was elected to the Chinese Academy of Engineering.

He has been engaged in mining engineering and geotechnical engineering research, dedicated to experimental study on rock rheology and rock mechanics. In 1978, he obtained the rock stress-strain diagram for the first time in China, proposed common fractured rock mechanics model, and formed a unique mining approach that impacts underground movement as well as the deformation calculation methods, on which he developed a series of computer software. He created and developed theory of random media with unified time-space, which were applied for protection of surface mining projects at mining underneath buildings, river and the railway, breaking the security pillar area on Taizi River forbidden by Soviet experts, exploited millions of tons of coal. This random media theory applies to iron ore, gold ore and phosphate rock, exploited a large number of mined ore underneath building, river and railway. Currently, the stochastic medium theory has been successfully applied to protect the surface of buildings above subway and shield tunnel construction project, which solved the expected-to-subside pre-hydrophobic surface of Beijing subway construction, which gained a huge economic and social benefits. His researches won one 3rd prize of National Science and Technology Progress Award, and many of them won the provincial and ministerial Science and Technology Progress Award. In 1994, he was awarded as the first "Star of Science" of Hunan Province, then named as "National Advanced Worker" in 2000.
