【摘要】 给出了爆炸衬砌的定义。介绍了爆炸衬砌技术的施工工艺和衬砌机理。推导出爆扩料仓半径的计算公式。分析了爆炸对周围土壤物理、力学性质的影响。指出装药药量及其在料仓中的位置是影响衬砌效果的重要因素。研究结果表明 ,砂浆衬砌外侧存在一个抗剪强度明显高于原状土体的土质外衬。爆炸衬砌在地下土层中形成的是一个砂浆与土体的复合衬砌更多还原

【Abstract】 In this paper,explosive lining is defined.The explosive lining technique,lining mechanism and its construction program are introduced.Formulas to calculate the radius of explosive enlarged cavity are derived.The influences of explosion on the physical and mechanical properties of the surrounding soil are analyzed.It is presented that the weight of charge and its location are important influencing factors on lining effectiveness.The study results indicate that there is a soil liner shell outside the mortar liner shell,and the shear strength of the soil liner is obviously higher than the undisturbed soil.The liner shell formed with explosive in underground soil is a composite one of mortar and soil.更多还原
