摘　　要：介绍滤纸法现场测量基质吸力的装置和测量结果,并与张力计测量结果、水土特征曲线算得的结果相比较,说明研制的装置简单实用。还介绍了双圈牌滤纸的率定过程和率定曲线,探讨了一些对测量精度有影响的因素。A device for field measurement of matric suction and its measured results are introduced in this paper. The results are compared with that from tensiometer method and SWCC, which illustrate that the device is simple and practical. The procedure of calibration and calibration curve of filter paper(Shuangquan brand)are also presented,and the influence factors on precision of the method are tested and analyzed in this paper. 
