| 摘 要： | 水利水电、矿业等工程在自然营造力作用下的水力劈裂边界条件与人工致裂不完全相同,有其自身的特点.在总结自然营造力作用下水力劈裂特点的基础上,根据研究的尺度不同,将水力劈裂研究分为岩体宏观的、综合的、统计意义上的水力劈裂和单裂纹的水力劈裂研究两种.分析了单裂纹内水流特性,将单裂纹内的水力劈裂分为两个阶段(或两种情况)分别进行研究,并将此问题得以简化,同时还提出了不同阶段裂纹内水流运动分析的模型.

| Abstract: | The hydraulic fracturing problems in fields of water conservancy and hydropower and mining are produced by natural hydraulic power. Its boundary conditions are different with them in artificial hydraulic fracturing applied to fields of petroleum and natural gas. The characteristics of hydraulic fracturing under natural power are generalized. The study level of hydraulic fracturing is divided into two based on study measure. The one is based on macroscopical, synthetical and statistical characteristics medium. The other is focused on a single fracture and a group of fracture with regular location. The characteristics of fracture flow are analyzed. In order to simplify the research, the hydraulic fracturing process of a single fracture can be divided two stage or two kinds. The different fracture flow models are proposed. |
