三峡工程中的若干力学问题

SOME PROBLEMS OF ENGINEERING MECHANICS IN THREE GORGES PROJECT

简要介绍了三峡水利枢纽工程概况，工程建设中主要技术难点，以及几个主要工程力学问题，包括流体力学、固体力学、二相流及爆破力学等问题．结合三峡工程侧重叙述岩石（体）力学应考虑的新问题．大型岩土工程是庞大的复杂系统，岩石力学涉及众多学科．建议应用系统工程的理论和方法研究岩石（体）力学，使其在国民经济中发挥更大作用，在岩石（体）力学研究中还需针对不同的目标、任务考虑各种非线性问题．因此，岩石（体）力学应与工程问题更紧密地结合．

This paper gives a brief account of the Three Gorges key water control project, the main technical difficulties in construction,as well as some important problems of engineering mechanics, including fluid mechanics,solid mechanics,two-phase flow and explosion mechanics etc. New problems of rock(rock masses)mechanics concerned with the Three Gorges Project are reviewed here,Geotechnical engineering in a large-scale is ahuge and complicated system and rock(rock masses)mechanics is related with avariety of disciplines.It is suggested that the theories and methods of system engineering should be used in the study of rock(rock masses) mechanics, con- sidering its important role in the national economy,It is also necessary to con- sider various non-linear problems for different objects and tasks in the study of rock (rock masses)mechanics.Therefore, the study of rock(rock masses)mechanics should be carried out hand in hand with that of engineering problems.
