【摘要】 随着我国交通、能源和水利水电等行业快速发展,在复杂地形地貌和地质条件下兴建大量岩土工程,尤其是深埋长隧道,原位地应力测量及其相关研究逾加重要。我国自20世纪60年代首次成功进行原位地应力实测以来,在地应力测量及相关研究方面已取得了长足进展。文中扼要介绍了我国地应力测量的发展历程,着重总结了在钻孔应力解除法、水压致裂法和其他常用原位地应力测量法及工程区初始地应力场分析研究方面所取得的进展,并结合我国区域构造应力环境和岩土工程的特点,对地应力测量和工程区初始地应力场研究方面的展望阐述了一点认识。更多还原

【Abstract】 With the development of traffic,energy and water resources and hydropower in China,in-site geostress measurement and correlative research are more and more important for many geotechnical engineering;especially for the deep and long tunnels,that will be constructed in the condition of complicated terrain and geology.After first success of in-site geostress measurement in the 1960 s,great developments have been made in the filed of in-site geostress measuring method and correlative research in China.In this paper the developments history of in-site geostress measurement in China is introduced briefly.The advances of borehole stress-relief method,hydraulic fracturing method,other in-site geotress measurement methods and inversion study of initial stress field are mainly introduced.In addition,the prospect of in-site geostress measurement and inversion method of initial stress field in China are described considering the development characteristic of geotechnical engineering in the future.更多还原
