The resonance rubblization technology can be adopted to reconstruct old concrete pavement and eradicate reflection cracking. This method fractures pavement into fragments quickly and directly casts asphalt on fractures, shortening time cost of reconstruction. Previous studies about this technology mainly concentrated on asphalt-casting methods, and the quality, stiffness, and flatness of reco…

Structural Health Monitoring of bridges has aroused the interest of many researchers on various disciplines. Our purpose in this paper is to make an overview on SHM of bridges from two different research areas: Civil and Communication Engineering. For the former part, we provide some insights into the objectives and the ways SHM of bridges is made. For the Communication Engineering side, we …
epairing or strengthening failing metallic structures traditionally involves using bulky and heavy external steel plates that often pose their own problems. The plates are generally prone to corrosion and overall fatigue. Fiber-reinforced polymer (FRP), a composite material made of a polymer matrix reinforced with fibers, offers a great alternative for strengthening metallic structures, especia…

In this paper, a prototype load test on cracked shield tunnel lining segment was conducted to study fracture properties of the segment with initial crack. Principle and process of the test were introduced, and test phenomena were detailedly depicted. Experimental results reveal that lining segment with initial crack finally shows the I-type fracture property, and the failure mode is dominated b…
Sandy pebble soil is widely distributed in our country. Lots of studies show that sandy pebble soil makes dynamic behavior not clear due to typical discreteness of gravels and random geometrical distribution. This paper quantitatively analyzes the law of the strength characteristics of sandy pebble tunnel surrounding rock under different density and moisture content conditions through large-s…
Resonant rubblization technology is often utilized to rehabilitate deteriorated condrete pavements. Vibrations induced by a resonant breaker would produce detrimental effects on lining structures in tunnel during rubblization construction. The in-situ experiments were carried out in Yangjiao Mountain Tunnel in Zheijiang Province, China. First, the characteristics of rubblization-induced vibrati…
