【摘要】：眾所周知，壓路機完成工作的標準主要靠檢測壓實度來確定。目前以壓實度來控制施工質(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)保證合格的壓實度，對防止壩體滲漏、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工作的重中之重。但是落后的傳統(tǒng)檢測手段使得修筑和維修工作變得耗時耗力、速度遲緩、精確度受人為影響大，急待得到改善。 綜上所述，智能快速無損壓實度檢測技術(shù)和道路無損檢測技術(shù)的開發(fā)就顯得尤為重要和迫切，一方面可以加快施工進度、提高壓實質(zhì)量，為壓實工作提供更好的控制和管理，另一方面可以為道路的養(yǎng)護提供精確的無損檢測技術(shù)，，以便及時檢測、排除隱患。針對此狀況，本文根據(jù)虛擬儀器的原理做出了以下研究： （1）以LabVIEW為開發(fā)平臺，借助美國NI公司的高速USB載體、加速度傳感器以及GPS信號接收器、橡膠錘等開發(fā)了一套智能壓路機隨車檢測系統(tǒng)和一套瑞利波道路無損檢測系統(tǒng)。 （2）智能壓路機隨車檢測系統(tǒng)實現(xiàn)了路基壓實質(zhì)量的快速無損檢測、壓路機速度、壓實遍數(shù)、壓實軌跡的GPS定位以及保存打印報表的功能，給現(xiàn)場壓實質(zhì)量檢測和控制帶來一定的方便；瑞利波道路無損檢測系統(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，從而對道路結(jié)構(gòu)分層、基層脫空、軟弱夾層進行無損檢測，有利于施工方和業(yè)主對已修道路進行檢測、校核評估，同時對于后期養(yǎng)護修復工作可以提供一定參考價值。 （3）分別利用智能壓路機隨車檢測系統(tǒng)和瑞利波道路無損檢測系統(tǒng)在新鄭市南水北調(diào)中線三標段施工現(xiàn)場和河南省焦作市博愛縣某公路段做了現(xiàn)場試驗，并與傳統(tǒng)試驗方法進行對比，結(jié)果證明了兩套智能檢測系統(tǒng)的可靠性、可行性，突出了智能、無損、方便快捷的優(yōu)點，不僅滿足了施工方和業(yè)主對智能檢測儀器的檢測要求也為將來的檢測工程智能化提供一定參考價值。 （4）通過現(xiàn)場試驗對兩套智能檢測系統(tǒng)進行的驗證結(jié)果做出評價和展望，希望智能檢測系統(tǒng)可以在現(xiàn)實施工環(huán)境中得到提倡和應(yīng)用，為公路和水利的建設(shè)維護事業(yè)做出貢獻。
[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.
