摘要
分析了国内外弯沉检测技术现状及发展动态,比较了静态弯沉量测、稳定弯沉量测及冲击荷载下动态弯沉量测等几种弯沉检测方法,详述了贝克曼梁弯沉检测与落锤式弯沉仪各自的特点与不足,最后介绍了FWD弯沉仪在工程检测中的应用实例,有利于FWD在国内的推广应用。
On the basis of analyzing the present condition and the latest developments of deflection testing techniques both at home and abroad, this paper assesses all kinds of deflection testing techniques, and studies the correction of the deflection values from FWD and Benkelman Beam and the application of FWD to highway inspection, which may help FWD find still wider application at home.
