Finite element modeling of slope wall stabilizer by nail and anchors   ?️ Jump to the contents (Click) 1. Introduction 2. Project Information 3. Conclusion 4. Reference           Introduction     Anchored walls have become popular in braced excavations because of a) the substantial progress in the technology and availability of high-capacity anchor systems, and b) the absence of interior obstructions that permit uninterrupted earth moving and thus improve the construction conditions of the underground portion of a building (Xanthakos, 1994). Figures 1 a ..read more

Now Register | FEM Analysis for Underground Mine Stability           Pile group settlement Analysis   The settlement behavior of a pile group has long been known to differ from the settlement of a single pile. A number of methods have been proposed to estimate the settlement of pile groups. Some of the methods give the maximum total settlement of pile group (refer as type A) while some other ..read more

Conclusion     We checked the model, the settings of the software package, and the calculation. On the surface, everything looks correct, but errors appear during the analysis. Familiar situation? Then this article is for you. Engineers often run into the same bugs.   It often happens that a non-linear calculation fails to converge after it has performed perfectly in the linear domain. Most ..read more

The Application of Deep Mixing Method for a River Wall and Finite Element Simulation     ?️ Click to jump 1. Introduction 2. Project Information 3. Constitutive Model Evaluation4. Finite Element Simulation5. Conclusion       Introduction     The ground improvement of the soft ground by mixing with cement is a very popular and effective method [3][2][1][7]. The stiffness, as well as strength of soft ground, can be improved by hydration and pozzolanic reaction between soil and cement [13]. The cement admixed clay (CA) is widely used in geotechnical projects, wh ..read more
