| 摘 要： | 水力劈裂在岩土工程、环境工程和石油工程中已得到很好地应用，但另一方面又会造成大坝渗漏破坏、浆液流失以及石油行业中经常遇到的浅水流动等严重后果。连续固体材料（如岩石）中的水力劈裂理论是建立在抗拉强度基础之上，对此，国内外的研究已经比较深入。而对于粒状材料中的研究尚处于起步阶段，仅有少数的试验和数值研究。本文综述了粒状材料中水力劈裂室内试验、现场试验、解析分析和数值模拟的研究成果，分析了当前研究中对这一现象认识的不足，并对今后可能的研究方向进行了预测。

| Abstract: | Hydraulic fracture has been widely used in geotechnical engineering,environmental engineering and petroleum engineering.However,it also causes such serious problems as dam leakage,grout efflux,and shallow-water flows in petroleum exploitation.Hydraulic fracture in continuous solid materials like rocks can be explained by the theory of tensile strength and it has been thoroughly studied.However,the mechanics of hydraulic fracture in granular materials is far away from clearness and only a few experimental an... |
