This study investigates the effect of shield tunnel grouting on excess pore pressure distributions around and ground consolidation settlement. First, it presents half-plane an unlined caused by based complex variable theory conformal mapping method. Second, analytical solution for soil is derived using transformation method Terzaghi–Rendulic. The drainage conditions lining are idealized into th...

[1] Brillouin scattering measurements on aluminous magnesium silicate perovskite, arguably the most abundant phase in Earth, have been performed to 45 GPa in a diamond anvil cell at room temperature, using methanol-ethanol-water and neon as pressure transmitting media. The experiments were performed on a polycrystalline sample of aluminous MgSiO3 perovskite containing 5.1 ± 0.2 wt.% Al2O3. The ...

Recycling and reusing plastic waste are key options for ameliorating its negative effects on the environment economy. This paper proposes evolutionary polynomial regression (EPR) as a powerful technique to predict compressibility behavior of sand high-density polyethylene (HDPE) mixtures. In investigation, series large-scale oedometer experiments were conducted. The results coefficients lateral...

inclined retaining walls with slopes less than perpendicular are appropriate candidates in several engineering problems. yet, to the knowledge of authors, only a few analytical solution for calculation of active earth pressure on such walls, which will be usually smaller than the same pressure on vertical ones, has been presented neither in research papers nor in design codes. considering limit...

In this study, we investigated the preconsolidation pressure (P C) of sedimentary soft rock and its relationship with brittle-ductile transition (BDT) pressure. We proposed a generalized G) suitable for both soil rock, which is defined in terms yield stress initial sediment structure under confined lateral compression. then explored digenetic effect on P G using 24 types. Next, BDT were verifie...
