A dam ant colony optimization (D-ACO) analysis of the overall stability of high arch dams on complicated foundations is presented in this paper. A modified ant colony optimization (ACO) model is proposed for obtaining dam concrete and rock mechanical parameters. A typical dam parameter feedback problem is proposed for nonlinear back-analysis numerical model based on field monitoring deformation...

according to the former researcher’s presented relations for flow through rock-fill porous media, the effects of physical characteristics was not studied separately. hence, due to the application of these relations, physical characteristics of porous materials effect must be investigated separately. in various constructed physical models of porous media, the effect of several variables such as ...

Clay, as a rock term, describes a soft, loose, earthy material containing particles with an average grain size of less than than 0.004 mm (4 mm) in the Wentworth grain size scale and less than 0.002 mm (2 mm) in most soil investigations. Clay is composed mostly of clay minerals, but may also contain quartz, feldspar, carbonates, ferruginous material, and other non-clay materials. All clays, apa...

We recently found that macrophages from RhoA/RhoB double knockout mice had increased motility of the cell body, but severely impaired retraction of the tail and membrane extensions, whereas RhoA- or RhoB-deficient cells exhibited mild phenotypes. Here we extended this work and investigated the roles of Rho signaling in primary human blood monocytes migrating in chemotactic gradients and in vari...

In order to safely and efficiently use soft rock aggregate cemented dams in red bed regions promote the development of widely sourced sand gravel dam materials, Jinjigou project China applied for first time construction material dams. This article further explores concept from conducting on-site direct shear tests research on ratios invents a new structure method by combining with rockfill. als...

Evaluating rock masses for dam foundations, especially heterogeneous (flysch), becomes imperative and requires accurate geomechanical classifications. The rocks at the Kanarwe river basin, a proposed site (Goma-Qazan near Khewata, Sura Qalat villages), mainly consist of interlaying massive carbonate Aqra Formation with flysch Tanjero Formation. Therefore, selecting appropriate types is challeng...

In the past thirty years many mining projects in Chile and Peru have used: (i) polymeric geomembranes (ii) design-and-build cutoff trenches, plastic concrete slurry walls, grout curtain systems to control seepage at tailings storage facilities (TSFs). Geosynthetics are a viable alternative TSF dam for clay cores or impermeable materials, mainly because of their marked advantages cost, installat...
