As has happened in various cases of earthquakes, the impact caused by each earthquake event varies, because shaking that occurs on ground is not only influenced distance and strength earthquake, but also local soil conditions which are related to amplification phenomenon. waves type thickness soil/sediment layer above bedrock. Reinforced concrete storey buildings designed withstand both vertica...

Statistical methods are presented to help evaluate cyclic test results in the small amplitude range. We utilize several statistical methods to extract from noisy feedback signals meaningful response parameters at very small strain levels. Previous work has shown that the uncertainty in the estimation of vertical strains is much greater than that for shear strains. Hence, we focus in this articl...

In this study, displacement experiments of isoproturon were conducted in disturbed and undisturbed columns of a silty clay loam soil under similar rainfall intensities. Solute transport occurred under saturated conditions in the undisturbed soil and under unsaturated conditions in the sieved soil because of a greater bulk density of the compacted undisturbed soil compared to the sieved soil. Th...

Leakage of underwater crude oil pipes causes severe pollution to soil and water, and results in great economic loss. To predict the diffusion area of spilled oil before it reaches the water's surface and to reduce the time required for emergency response, numerical simulations were conducted on underwater spilled oil diffusion of bare crude oil pipes using FLUENT software. The influences of wat...

The article compares the indicators of experimental and calculated bearing capacity bored piles installed using DDS technology, according to static tests normative calculations. also presents results compression soil samples around placed Drilled Displacement System (DDS) method. authors established dependence deformation properties soil, such as modulus deformation, angle internal friction adh...

investigating the parameters influencing the behavior of buried pipelines under dynamic loading is of great importance. in this study the soil structure interaction of the pipelines with the surrounding soil was addressed using shaking table tests. wave propagation along the soil layers was also included in the study. the semi infinite nature of the field was simulated using a laminar shear box...

Due to invisibility and complexity of the underground displacement monitoring, there exit few practical monitoring sensors capable of monitoring the underground horizontal and vertical displacements simultaneously. A novel electromagnetic underground displacement sensor able to monitor both the horizontal and the vertical displacements was proposed in our previous studies and abbreviated as the...

In this paper, to optimize the “Characteristic Straight Line Method” which is used in the soil displacement analysis, a “best estimate” of the geodetic leveling observations has been achieved by taking in account the concept of ‘Height systems”. This concept has been discussed in detail and consequently the concept of “height”. In landslides dynamic analysis, the soil is considered as a mosaic ...

several relationships to assess at-rest pressure coefficient in retaining walls, have been developed by different researchers. these suggested relationships are generally a function of mechanical soil parameters such as internal friction angel, poison ratio and over-consolidation ratio. in integral bridges, however, this coefficient is also a function of many other parameters other than soil ch...
