目前,土动力学的国际学术活动包括国际学术会议频频地在世界各地展开。基于半空间已被采用为土的数学模式,故土动力学的一个重要内容就是半空间理论。近代大容量、超高速动力机器的出现对振动控制提出了更严要求,而能满足这一要求的就是半空间理论。且在地震工程中半空间理论又是研究结构与地基共同作用的利器。这种情况迫使美、日等工业先进国家都不得不深入地研究半空间理论。即使苏联在动力基础理论方面历来以温克莱地基为土的数学模式,近年也开始移植半空间理论的现代成果对原有体系
At present, international academic activities in soil dynamics, including international academic conferences, are frequently carried out throughout the world. Based on the fact that half-space has been adopted as a mathematical model of soil, an important part of soil dynamics is the half-space theory. The emergence of large-capacity, ultra-high-speed power machines in modern times puts stricter requirements on vibration control. The half space theory can satisfy this requirement. In the earthquake engineering, the half-space theory is also a tool to study the joint action of the structure and the foundation. This situation has forced the United States, Japan and other advanced industrial countries to have to study the half-space theory in depth. Even though the Soviet Union has always been based on the mathematical model of the foundation of dynamic foundation in terms of the foundation of Winklee, in recent years it has also begun to transplant the modern achievements of the semi-space theory to the original system.
