公路路基强度和稳定性的快速无损检测

Quick Non-destructive Testing of Strength and Stability of Highway Roadbed

公路路基强度检测参考标准是求得弯沉盆参数,在最小二乘意义上,模量反算是求得理论弯沉盆与实际测得弯沉盆之间的最佳拟合的重要计算手段。此法不仅具有一般线性规划问题的数值不确定性,还具有高复杂度和高维度的特点。在充分了解模量反算本质的基础上,介绍了新型的回弹模量测试方法——PFWD,并提出了与之相适应的自适应信息遗传模量反算法。

The reference standard of the strength testing of highway roadbed is to calculate the deflection basin parameter,back calculation of modulus is the best fit to calculate the theory and practice of deflection basin in the sense of least square.This method not only has numerical uncertainties of general linear programming problem,but also has characteristics of high complexity and high dimension.On the basis of fully understanding the nature of back calculation of modulus,and introducing new test method of rebound modulus--PFWD,and providing corresponding back calculation of self-adaption information genetic modulus.
