Abstract Slope protection has always been a major concern in highway construction and later operation. Ecological technology is widely used slope, which takes into account functions of protection, ecology, landscape. mainly to improve the stability slope through combination supporting structure plants, vegetation restoration can reduce negative impact construction. In this paper, latest research progress ecological was first reviewed identify main process types, revealed mechanism...
Carbonaceous mudstone aggregates are prone to disintegrate produce alkaline hydrosols under dry and wet cycles, which affects the planting performance of vegetation concrete (VC). To improve carbonaceous aggregate (CMAVC), while considering soaking time concentration main factors influencing effect pH-reducing, pH reduction improvement tests, uniaxial compressive tests different were carried out, verified by microscopic tests. The results show that ferrous sulfate oxalic acid reduced CMAVC...
Embankments filled with disintegrated carbonaceous mudstone (DCM) are prone to uneven settlements because of water-softening property and secondary disintegration mudstone. To address this problem, nano-Al²O³ cement were proposed in study improve the strength DCM. Many nano-Al²O³- cement-modified DCM (NACDCM) specimens various contents prepared. Unconfined compression tests triaxial performed examine strengths NACDCM under different conditions. Moreover, X-ray diffraction (XRD) analyses...
Slopes with carbonaceous mudstone (CM) are widely distributed in the southwest of China and have experienced numerous geological disasters special climate, especially rainfall conditions. Therefore, novel materials to stabilize CM slopes attracted increasing interests. However, developing ultra-stable cost-effective additives for is still a great challenge. Herein, hydrophobic polymeric material (polyvinylidene fluoride, PVDF) investigated as an additive enhance mechanical strength long-time...
Under the effect of load and seasonal rainfall, disintegrated carbonaceous mudstone (DCM) softens further disintegrates, causing large settlements even collapses DCM embankments. For this reason, some treatments should be taken to improve engineering performance DCM. In study, four materials including sodium alginate (SA), calcium chloride (CaCl2), bentonite nano-Al2O3 were jointly used as modifiers treat The influences each modifier component on unconfined compressive strength (UCS),...
By studying tunnel face images collected during a highway excavation, we establish the classification system of photolithography by MATLAB programming. According to rock mass index (rock block size or RBI) concept, 19 virtual lines are arranged in turn contour line, and difference brazier structure is evaluated synthetically RBs radial direction face. Based on structure, distribution comprehensive (Z-RBI) obtained through evaluation surface, corresponding relationship between Z-RBI type...
