Soil nailing wall with vertical nails to displacement reduction: Brazilian Practice

چکیده
Most of the time, geotechnical engineering interventions require solutions that necessarily aim for better use available space. Many slope stabilization techniques were developed following assumption, and one most applied procedures in Brazil is soil nailing reinforcement. These are constantly improving. Consequently, a continuous study design behavior nails important. The technique vertical reinforcement recent Brazilian scenario. Nowadays, some constructors started to them near face when stabilizing huge excavations. This paper aims verify nails’ efficiency reducing horizontal displacements. We present three numerical modeling analyses using finite elements method (FEM). proposed model approximately 18m high homogeneous subsoil São Paulo city. Comparing situations with without nails, as if an inclined (slope), results showed adding those could reduce

Hopper Wall Simulation in ANSYS to Determine Displacement Due to Single Ball Impact
Deformation of the silo wall due to the single ball impact is modeled in ANSYS. The material in silo, as a Winkler bed, is replaced by spring-damper elements and the spring stiffness and damper coefficients are evaluated of the granular material and wall properties. The granular material deformation under the specified force is measured to evaluate the granular stiffness to be used for determin...
متن کاملInvestigating Stabilized Excavations Using Soil Nailing Method in Urban Context
There are various methods for stabilizing excavations in urban areas which one of them is the nailing method. Designing a nailing system and analyzing the performance of excavations is done by various software applications. One of these computer programs is PAXIS software which run based on the finite element method (FEM). In the present study, a numerical analysis of the performance of t...
متن کاملParaffin-pdms Composite Thermo Microactuator with Large Vertical Displacement Capability
We have micromachined and tested the first paraffin–PDMS composite thermal microactuator having multi shot large vertical displacement capabilities (~160 μm for 1 mm diameter device). A solid to liquid phase change of trapped paraffin into the PDMS is used to create a large volume dilatation of the composite (18%, for a temperature varied from 20 to 80 °C). The elasticity of the PDMS ensures th...
متن کاملDisplacement of Surface Monuments: Vertical Motion
Several measurements of vertical ground motion at Pition Flat Observatory, California, indicate the overall weakness and instability of the Earth's weathered surface with respect to the underlying rock. Cumulative long-period motions of order 0.5 mm per year dominate these records, though smaller elastic deformations caused by precipitation loading, atmospheric loading, and tidal strains are ev...
