摘　　要：确保城市道路的安全运行,关系到城市交通的有序工作,对于城市经济发展和居民日常生活具有重要意义。该文针对道路路基安全问题,提出一种基于主成分分析的路基压实均匀性检测方法。从弯沉值指标、动刚度指标、回弹模量指标和弹性模量指标构建出6个主成分,进而根据主成分分析的过程得到各指标与主成分的因子关系。以邯郸市20个路段的路基为对象展开实验,检测结果显示,各路段的路基表现出不同的压实均匀性,有的可以继续正常工作,有的需要进行维修维护处理。该文研究表明运用主成分分析,可以得到各路段路基压实均匀性的量化检测结果,为市政工程的具体处理提供依据。Ensuring the safe operation of urban roads is related to the orderly work of urban traffic and is of great significance to economic development and residents'daily life in the city.In this paper,aiming at the problem of road subgrade safety,a method of subgrade compaction uniformity detection based on principal component analysis is proposed.Six principal components are constructed from deflection value index,dynamic stiffness index,rebound modulus index and elastic modulus index,and then the factor relationship between each index and the principal component is obtained according to the process of principal component analysis.Taking the roadbed of 20 road sections in Handan as the object to carry out the experiment,the test results show that the roadbed of each section shows different compaction uniformity,some can continue to work normally,whileothers need maintenance.The study of this paper shows that the quantitative testing results of roadbed compaction uniformity of each road section can be obtained through principal component analysis,which provides a basis for the specific treatment of municipal engineering.
