THE RESEARCH ON RAMMED-EARTH MATERIAL COMPRESSIVE STRENGTH NONDESTRUCTIVE TESTING FOR FUJIAN TULOU(EARTH-BUILDING)
-
摘要: 针对福建土楼墙身夯土材料强度的无损检测方法进行研究。通过对回弹仪工作原理以及夯土材料强度的研究,对回弹仪进行加大弹击杆端的改进以提高其测试精度,结合夯土试块的抗压强度试验建立起不同年代夯土材料专用测强曲线。并通过现场实测,验证改进后回弹仪的适用性,为在役土楼的现场无损检测打下了基础,有助于进一步完善土楼保护措施。Abstract: It was studied the nondestructive testing methods of rammed-earth material strength of tulou wall. Through the research of working principle of the rebound hammer and rammed-earth material mechanical properties，the area of the rod end of the rebound hammer was enlarged to improve the detection precision. Combined with the compressive strength test of rammed earth cubes，the testing strength curves of rammed-earth material in different chron were set up. And through the field test，it was verified the applicability of the improved rebound hammer, which laid a foundation for field detection of the tulou (earth-building) in service，and contributed to improving protection measures.
