| 6. | Because the distribution of soft soil is very widely , the sliding strength of soft soil is low , the moisture content of soft soil is rich , and the compression of soft soil is large , the handling of soft base is an important problem
这是由于软土抗剪强度低，含水量大，压缩量大，路堤建成后不可避免产生不均匀沉降，影响路面平整度，这样在行车时会出现跳车现象，既不舒服，又影响安全。 |
| 7. | Experiment results prove that this algorithm is a practical and effective method , with which the ideal cross - section curve can be acquired . the result is coincidence to the standard iri ( the international roughness index ) and meets the necessity
实验结论：基于阵列信号处理和小波降噪的算法应用于路面平整度检测可以得到较理想的断面曲线，换算国际平整度指标iri与标定较吻合，符合处理要求。 |
| 8. | Beginning from the effecting factors of high grade road roughness , this paper consulted many recent domestic and foreign texts and field observation data of high grade roughness and explore the transfer principle of road roughness and probability statistics
本文查阅了国内外最新文献和高等级公路施工现场的观测资料，从影响高等级公路路面平整度的因素出发，揭示了路面平整度的传递规律及平整度的概率统计规律。 |
| 9. | Concrete spreader is one of the machines that have been widely used for road pavement nowadays , and the automated leveling device ( ald ) takes an important role in the performance of the whole machine , to get the flatness of the road and to improve the performance of the pavement
混凝土摊铺机是近些年流行的一种路面机械,其调平装置在整机性能中占有很重要的地位,是保证路面平整度、提高公路摊铺质量的关键。 |
| 10. | Based on the above numerical procedure , parameter study , including the vehicle velocity , damping of the bridge , road surface roughness , and constrained freedom of the bridge , is conducted to investigate the influence of some important bridge and vehicle parameters on the impact ratio of the bridge
基于上述方法，本文深入分析若干物理参数包括车速、桥梁阻尼、路面平整度和桥梁约束条件等对桥梁冲击系数的影响。 |
