【摘要】：眾所周知，壓路機(jī)完成工作的標(biāo)準(zhǔn)主要靠檢測(cè)壓實(shí)度來(lái)確定。目前以壓實(shí)度來(lái)控制施工質(zhì)量主要用在水利工程中土石壩的建設(shè)和公路工程的修筑中。合格碾壓工作質(zhì)量可以為水利工程壩體建設(shè)保證合格的壓實(shí)度，對(duì)防止壩體滲漏、保證壩體安全起到重要作用，而在公路工程中可以提高道路的承載力，并防止沉陷，水分滲透等。另外隨著公路的大規(guī)模修筑，公路的維修工作也成為公路管理部門(mén)工作的重中之重。但是落后的傳統(tǒng)檢測(cè)手段使得修筑和維修工作變得耗時(shí)耗力、速度遲緩、精確度受人為影響大，急待得到改善。 綜上所述，智能快速無(wú)損壓實(shí)度檢測(cè)技術(shù)和道路無(wú)損檢測(cè)技術(shù)的開(kāi)發(fā)就顯得尤為重要和迫切，一方面可以加快施工進(jìn)度、提高壓實(shí)質(zhì)量，為壓實(shí)工作提供更好的控制和管理，另一方面可以為道路的養(yǎng)護(hù)提供精確的無(wú)損檢測(cè)技術(shù)，，以便及時(shí)檢測(cè)、排除隱患。針對(duì)此狀況，本文根據(jù)虛擬儀器的原理做出了以下研究： （1）以LabVIEW為開(kāi)發(fā)平臺(tái)，借助美國(guó)NI公司的高速USB載體、加速度傳感器以及GPS信號(hào)接收器、橡膠錘等開(kāi)發(fā)了一套智能壓路機(jī)隨車(chē)檢測(cè)系統(tǒng)和一套瑞利波道路無(wú)損檢測(cè)系統(tǒng)。 （2）智能壓路機(jī)隨車(chē)檢測(cè)系統(tǒng)實(shí)現(xiàn)了路基壓實(shí)質(zhì)量的快速無(wú)損檢測(cè)、壓路機(jī)速度、壓實(shí)遍數(shù)、壓實(shí)軌跡的GPS定位以及保存打印報(bào)表的功能，給現(xiàn)場(chǎng)壓實(shí)質(zhì)量檢測(cè)和控制帶來(lái)一定的方便；瑞利波道路無(wú)損檢測(cè)系統(tǒng)是利用瑞利波在不同的介質(zhì)中的頻散特性以及傳播速度不同，從而對(duì)道路結(jié)構(gòu)分層、基層脫空、軟弱夾層進(jìn)行無(wú)損檢測(cè)，有利于施工方和業(yè)主對(duì)已修道路進(jìn)行檢測(cè)、校核評(píng)估，同時(shí)對(duì)于后期養(yǎng)護(hù)修復(fù)工作可以提供一定參考價(jià)值。 （3）分別利用智能壓路機(jī)隨車(chē)檢測(cè)系統(tǒng)和瑞利波道路無(wú)損檢測(cè)系統(tǒng)在新鄭市南水北調(diào)中線(xiàn)三標(biāo)段施工現(xiàn)場(chǎng)和河南省焦作市博愛(ài)縣某公路段做了現(xiàn)場(chǎng)試驗(yàn)，并與傳統(tǒng)試驗(yàn)方法進(jìn)行對(duì)比，結(jié)果證明了兩套智能檢測(cè)系統(tǒng)的可靠性、可行性，突出了智能、無(wú)損、方便快捷的優(yōu)點(diǎn)，不僅滿(mǎn)足了施工方和業(yè)主對(duì)智能檢測(cè)儀器的檢測(cè)要求也為將來(lái)的檢測(cè)工程智能化提供一定參考價(jià)值。 （4）通過(guò)現(xiàn)場(chǎng)試驗(yàn)對(duì)兩套智能檢測(cè)系統(tǒng)進(jìn)行的驗(yàn)證結(jié)果做出評(píng)價(jià)和展望，希望智能檢測(cè)系統(tǒng)可以在現(xiàn)實(shí)施工環(huán)境中得到提倡和應(yīng)用，為公路和水利的建設(shè)維護(hù)事業(yè)做出貢獻(xiàn)。
[Abstract]:As we all know, the standard of compaction is determined by measuring compactness. At present, the compaction degree is used to control the construction quality mainly in the construction of earth and rock dams in water conservancy projects and in the construction of highway projects. The quality of qualified roller compaction can guarantee the qualified compaction degree for the construction of water conservancy dam body, and play an important role in preventing dam body leakage and ensuring dam body safety. In highway engineering, the bearing capacity of road can be improved and the settlement can be prevented. Water penetration, etc. In addition, with the large-scale highway construction, highway maintenance has become the most important work of highway management. However, the backward traditional detection means make the construction and maintenance work become time-consuming, slow, the accuracy is greatly affected by human, urgent need to be improved. To sum up, the development of intelligent rapid nondestructive compaction testing technology and road nondestructive testing technology is particularly important and urgent. On the one hand, it can speed up construction progress, improve compaction quality, and provide better control and management for compaction work. On the other hand, it can provide accurate nondestructive testing technology for road maintenance, in order to detect and eliminate hidden dangers in time. According to the principle of virtual instrument, this paper makes the following research: (1) with LabVIEW as the development platform, with the help of American NI high-speed USB carrier, acceleration sensor and GPS signal receiver, The rubber hammer has developed a set of intelligent road roller carrying detection system and a Rayleigh wave road nondestructive testing system. (2) the intelligent roller carrying inspection system has realized the fast nondestructive testing of roadbed compaction quality and the road compactor speed. The number of compaction times, the GPS positioning of compaction track and the function of saving print report form bring some convenience to the field compaction quality detection and control. Rayleigh wave road nondestructive testing system uses Rayleigh wave in different media of different dispersion characteristics and different propagation speed, thus the road structure is stratified, the base layer is empty, and the soft interlayer is nondestructive testing. It is advantageous for the construction side and the owner to check and evaluate the roads that have been repaired, At the same time, it can provide a certain reference value for the later maintenance and repair work. (3) the intelligent road roller carrying detection system and Rayleigh wave road nondestructive testing system are used in the construction of the third section of the middle line of Xinzheng South-to-North Water transfer Project, respectively. Field tests were conducted on the spot and a section of a highway in Boai County, Jiaozuo City, Henan Province. Compared with the traditional test methods, the results prove the reliability and feasibility of the two sets of intelligent detection system, and highlight the advantages of intelligence, nondestructive, convenient and fast. It not only meets the inspection requirements of the construction side and the owner to the intelligent testing instrument, but also provides a certain reference value for the future intelligent testing engineering. (4) the verification of the two sets of intelligent detection system through the field test. To make an assessment and a vision, It is hoped that the intelligent detection system can be advocated and applied in the real construction environment and contribute to the construction and maintenance of highway and water conservancy.
