This work developed prediction models for maximum dry unit weight (γd,max) and optimum moisture content (OMC) compacted soils in Ceará, Brazil, ba M Winnie the Pooh sed on index physical properties. The methodology included data from used construction of 15 dams with available information regarding laboratory tests interest. Correlations were using non-linear regression, 169 results (83 training 86 validating models), which presented a R2 0,763 MoPesm (prediction model γd,max) 0,761 MoTuo...
This paper analyzes the problem of fracture in soils using linear elastic mechanics theory. Six cases practical interest are investigated where soil is subjected to different critical conditions that may produce cracks. To model phenomenon crack propagation, a two-dimensional finite element program used. In all cases, properties clays Valley Mexico was The self-weight considered as main cause geostatic stresses medium. Based on results from previous studies, value stress intensity factor...
The present work intends to demonstrate the advantages of considering transient flow regime in stability analysis upstream slope for rapid drawdown situation a homogeneous earth dam. Upstream evaluations were carried out, pore pressure and suction from while simulating reservoir. comprised different geometries (from 1V:1.1H 1V:2.5H) heights varying 10 m 50 m, as well several low permeability materials (SM, SM-SC, SC, ML, ML-CL, CL, MH CH). In addition, equations relating safety factor such...
Al utilizar pilotes para la concepción de un proyecto, dependiendo distancia entre ellos, el comportamiento uno interfiere con otro. Esto ocurre tanto en términos capacidad carga como relación asentamientos. Investigaciones sobre efecto grupo suelos tÃpicos Fortaleza son escasas, lo que justifica y motiva este trabajo. El objetivo presente investigación es evaluar escavados perfil suelo granular, a los ocurren subsuelo ciudad fortaleza -Ceará- Brasil. Para esto se ejecutaron 26...
