从模拟实验的初步结果看中国地壳的受力状态

地壳表面的许多构造轮廓均与基底断裂(即深大断裂)的破裂程度和其所切成块体的形状有直接联系。对导致构造体系形成的动力,早在1926年,李四光教授就开始了这方面的研究,并取得了创造性的成就。在这以后,张文佑同志对于基底断裂形成的力学机制及其对于盖层构造的控制也先后作了一些工作。

PRELIMILARY REPORT ON THE STRESS DISTRIBUTION IN THE EARTH’CRUST BENEATH THE TERRITORY OF CHINA BY MODEL EXPERIMENTS

The analyses of recent geological and geophysical data indicate that tectonic structures in China are chiefly characterized by the function-fault blocks in forms of rhombic massives both in the eastern and western parts of China.In this report an attempt is made to investigate the mechanism of formation of regional stretures in China, basing on the results of model experiments and geome-chanical analyses as well as geohistorical developments. In addition, the special boundary connection of structural features in this country with adjacent countries and Pacific belt is also discussed.
