“…Natural fiber reinforced composites dependent on oil-based thermoplastics, or thermosets have utilized in different industrial segments, mostly in automobiles, furniture, agriculture, flammability, and environmental engineering applications [5][6][7]. Nowadays, also in the development of the construction industry, as well as unremittingly opening new industrial possibilities, are broadening day by day [8]. All petroleum-based thermoplastic polymer is not well amiable with the environment because of its non-biodegradable property, which causes numerous environmental problems [9].…”

Green composites using thermoplastics and thermosets got immense popularity long back when it newly introduced to the industry due to diminishing reliance on oil-based or gasoline materials, which causes numerous environmental problems. In this paper, bio-composites mechanical, chemical, thermal, and degradation properties of hybrid jute and coir fibers reinforced polylactic acid (PLA) investigated. Throughout the fabrication procedure of biocomposites, jute, and coir fibers characterized into three different categories raw, alkali-peroxide, and alkali-silane combined chemical treatments followed a design containing in a total of ten optimized samples. Jute and coir fibers were mixed with a solution of polycaprolactone (PCL) for better fiber-matrix adhesion prior to fabrication. The mechanical properties of alkali-silane treated reinforced fibers biocomposites improved compared to untreated fibers, which exhibited for fiber contents 40% an increase of respectively 32.8% by tensile strength 25.95% by tensile modulus, 24.58% by flexural strength, 23.64% by flexural modulus, and 26.08% by impact strength. Besides, moisture absorption, thickness swelling, thermal stability (TG), and surface chemistry analysis (FTIR) properties investigated, according to fiber-matrix contents ratio, hot-pressing time, temperature, and pressure to identify the effect of biocomposites due to chemical treatments. Moreover, the fiber surface effect of chemical treatments and interfacial adhesion morphologies observed using SEM. Eventually, alkali-silane combined optimized samples demonstrated the most desirable result in every aspect. In addition, a 90 days burial degradation performed to see the degradation flow of the biocomposites.

“…A discontinuous structural plane, such as rock joints and fractures, is an important rock mass component that is an essential reason why a rock mass, as an engineering medium, has different characteristics from other engineering media [1][2][3]. e existence of a structural plane damages the continuity and integrity of a rock mass, causes a rock mass to have unevenness and anisotropy, and greatly reduces the strength and stability of an engineering rock mass [4][5][6][7][8][9][10][11]. In practical engineering, the surface morphology of a discontinuous structural plane in a natural rock mass is irregular [12][13][14].…”

e surface morphology of a discontinuous structural plane in a natural rock mass is irregular. In studies on the shear strength of discontinuous structural planes, Barton introduced the joint roughness coefficient (JRC) to describe and calibrate the morphological characteristics of a rough structural plane. To describe Barton's typical rough profile model, researchers commonly conduct a comparison based on a standard curve.is approach does not guarantee graphic precision. With subjective comparison reference drawing, the size and angle of a structural plane cannot be quantitatively controlled, and small bumps cannot be described. When the influence of the roughness coefficient of a rock surface is discussed, errors are caused by comparing Barton's typical roughness profile model and a general structural surface model. is paper proposed a new method to simulate Barton's typical structural surface. A numerical model of a complex structural plane is built automatically. e effects of cohesion and internal friction angle on the shear strength of the structural plane are discussed by changing the value of the shear strength parameters.

“…Previous research shows that the accumulation of irreversible deformation of rock, growth trend, and total fatigue under cyclic loading is directly related to fatigue damage [23]. According to the standard requirements [24,25], saturated rock uniaxial compressive strength is about 50 MPa, and the constant loop unloading test was carried out considering the frequent emergence of reservoir earthquake with low frequency and magnitude [26]. e lower and upper limits of Advances in Civil Engineeringcyclic load stress are, respectively, de ned as 10 MPa and 20 MPa, which refer to 20% and 50% of rock uniaxial compressive strength [27].…”

During the reservoir operation process, the long-term security and stability of the bank slope is affected by dynamic response characteristics of its seismic action directly. Aimed at the typical bank slope existing in the actual reservoir environment, an experiment considering reservoir water level fluctuation and soaking-air-drying cyclic water-rock interaction has been designed and conducted while the cyclic loading test was performed in different water-rock cycles. Research results indicate the following: Firstly, in the process of water-rock interaction, the dynamic characteristics of sandstone show evident degradation trend, with the increase of the damping ratio and Poisson's ratio and decrease of dynamic elastic modulus, and the former six water-rock cycle degradation effects are particularly obvious. Secondly, the numerical analog computation analysis of dynamic response in typical bank slope shows that as the water-rock interaction period is increased, the dynamic response of the slope hydro-fluctuation belt zone increases gradually, while the other parts weaken. irdly, under the long-term water-rock interaction process, the hydrofluctuation belt zone gradually becomes a "soft layer" which is sensitive to the earthquake effect and dynamic response, resulting in a direct influence on long-term seismic performance of the bank slope. erefore, it is necessary to make better protection for the bank slope hydro-fluctuation belt zone.
