In this paper, the compression drive mechanism, which can be considered as most related oil mechanism with reservoir geomechanical properties, has been investigated. The constant total vertical stress on and uniaxial compaction zero lateral strain are two main assumptions in conventional modeling. These not considering arching, leads to a reduction also affects distribution of horizontal stress...

The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...

The initial-value problem for a class of Volterra functional differential equations— of sufficient generality to encompass, as special cases, ordinary differential equations, retarded differential equations, integro-differential equations, and hysteretic differential equations— is studied. A self-contained and elementary treatment of this over-arching problem is provided, in which a unifying th...

A girl presented at 6 weeks of age with failure to thrive and arching of the back. She had various dysmorphic features, hepatosplenomegaly, and developmental delay. The electroencephalogram and cranial ultrasound were abnormal, and a computed tomogram showed lissencephaly and apparent agenesis of the corpus callosum. Because of frequent aspiration she became oxygen dependent. She later develope...

Piles have been widely used to improve the bearing capacity of soft foundation. The existing research obtains significant findings on load transfer mechanism for rigid piled embankments. However, limited studies focused deep cement mixing (DCM) embankment. To grasp characteristics DCM embankments, a three-dimensional numerical simulation was conducted in this study, which validated by measureme...

Construction on weak subsoil is a reoccurring challenge for engineers nowadays, which various different solutions are available. Geosynthetics getting more and popular one of their most widely used application reinforcement. Several types geosynthetics can be used, the well-known vertical drains geogrids. Prefabricated accelerating consolidation in oversaturated soils with high water content as...
