post failure analysis of massive structure infers that soil-structure interaction (ssi) is a crucial phenomena influencing seismic response of massive structures. cable-stayed bridge’s popularity and numbers are increasing now-a-days because of economical longer span & aesthetic good look. the current paper examines the effect of depth of foundation on seismic response of cable-stayed bridg...

The aim of this study was to produce mulch by combining natural mineral and organic substances in order to reach soil stabilization and improve soil physical and mechanical properties in Koopal area. The effects of organic mulch (at 3 levels of O1: combination of 1% sugarcane bagasse biochar+0.5% gum Arabic+0.5% gelatin; O2: combination of 3% sugarcane bagasse biochar+1% gum Arabic+1% gelatin; ...

Few studies have been published on the dynamic centrifuge model test of cohesive soil under earthquake action. The seismic response foundation and tunnel was studied by experiment numerical modelling. Through a comparison acceleration results pore pressure displacement foundation, influence is discussed. weak position predicted effective show that: (1) Under Parkfield wave, natural frequency wi...

This thesis develops analytical solutions for estimating the bending moments and axial loads in a buried pipeline due to ground movements caused by tunnel construction in soft ground. The solutions combine closed-form, analytical solutions for tunnel-induced, free-field ground deformations in a plane orthogonal to the heading (Pinto and Whittle; 2001) with Winkler models for pipe-soil interacti...

this paper presents a description of the equipment, testing procedure, and methodology to obtain ground mechanical parameters. the p-y curves for laterally loaded piles are developed. methods for the development of p-y curves from pressure meter and dilatometer (dmt) test are described. p-y curves are used in the analysis to represent lateral soil-pile interaction. the pressure meter offers an ...

This study investigates the effect of shield tunnel grouting on excess pore pressure distributions around and ground consolidation settlement. First, it presents half-plane an unlined caused by based complex variable theory conformal mapping method. Second, analytical solution for soil is derived using transformation method Terzaghi–Rendulic. The drainage conditions lining are idealized into th...

We study the influence of Coulomb interaction on the thermoelectric transport coefficients for a metallic single-electron transistor. By performing a perturbation expansion up to second order in the tunnel-barrier conductance, we include sequential and cotunneling processes as well as quantum fluctuations that renormalize the charging energy and the tunnel conductance. We find that Coulomb inte...

Based on the existing monitoring data, this paper uses matured data method to analyze, predict long-term settlement of subway shield tunnel, and comprehensively analyzes tunnel in saturated sand layer Zhengzhou. Logical curve model, etc. is used separately Zhengzhou metro tunnel. Combining prediction results summarize characteristics a model suitable for sandy soil area represented by obtained,...

We theoretically study effects on tunnel magnetoresistance ~TMR! of spin configurations localized within insulating barriers. Two cases are treated herein: interaction between a tunneling electron and an isolated classical spin being canted at an angle to the magnetization axis of the ferromagnetic leads, and interaction between a tunneling electron and many quantum spins within the insulating ...
