摘要
The ground fissures in Longyao County are the typical surface disaster in North China region. They not only caused eroding, collapsing, extension fracturing,faulting, cracking and other geological disasters on the earth’s surface, but also caused severe economic losses in the local agricultural production, engineering construction and the lives of the people. This paper aims to reveal their genetic nature. It is based on geological investigation, monitoring and measuring, trenching, physical exploration. It studies the development characteristics of the Longyao ground fissures. They include the planes, profiles, deep and activity aspects. The paper summarizes the laws of ground fissures. Finally the ground fissure mechanism is analyzed from their crack-pregnant environment, crack-opening conditions and cracking process.
