In the last five decades, rise of plastic industry led to increase in waste environment, therefore scientists were thinking reduce by recycling plastic. On other hand, there is a problem collapse gypseous collapsible soil upon wetting. this paper, one methods adopted improve mixing with 1% fiber shear strength and collapsibility at state saturation or The used classified as SW-SM, gypsum conten...

The leakage of oil products which results in making the soil pollute or impure and alter its physical mechanical properties due to presence hydrocarbons it. Those cannot be passed into through pores become congest on top land. Hence it is necessary indicate know geotechnical contaminated soil. Recently modern technique an encompassing laboratorial system intends encourage improve high level det...

To investigate some geotechnical characteristics of the soils in a chosen area Abu Al-Khasib city, Basrah Governorate, southern Iraq, nine boreholes that range depth from 10 to 32 meters were drilled. Based on results standard penetration tests and particle size analysis Quaternary deposits, which extend vertically meters, are divided into 8 layers with varying bearing capacities depending thei...

The simulation of structural and geotechnical systems is a critical step in their design and assessment. The purpose of an earthquake simulation is to estimate the performance of the system under seismic excitation or loads that represent the effects of an earthquake. Structural and geotechnical simulation has a long history of development in earthquake engineering. The computation required to ...

the uniaxial compressive strength (ucs) of intact rocks is an important geotechnical parameter required for designing geotechnical and mining engineering projects. obtaining accurate estimates of the rock mass ucs parameter throughout a 3d geological model of the deposit is vital for determining optimum rock slope stability, designing new exploratory and blast boreholes, mine planning, optimizi...

Blast-induced seismic wave is very important to theory study of structure damage and stability analysis of corresponding geotechnical engineering; however it is not well solved. Based on measured data of Lafarge quarry, shortcoming of traditional analysis method is pointed out. Wavelet analysis method is presented to describe spectral characteristics and energy distribution of blast-induced sei...

Modern ground-water flow models, geotechnical studies, and science-based land-use planning require knowledge of the distribution of surficial earth materials from land surface to the top of bedrock (e.g., Masterson and others, 1997a,). To be useful, modern geologic maps must portray such information three dimensionally in a way that is consistent with the regional stratigraphic framework, geote...

The research area is located at Batu Hijau Mine – PT Amman Mineral Nusa Tenggara, administratively located at the southwestern of Sumbawa, West Nusa Tenggara Province – Indonesia. The research area is controlled by tectonism in accordance to close with the active tectonic plate at southern part of this island. The presence of the active tectonic regime causes of the rich deposit of ore minerali...

The characteristic of expansiveness represented by swelling pressure is considered as major parameter in design of engineering structures. In order to determine the potential expansion, the swelling pressure experiments are usually conducted. In the present study, neuronets have been used to predict swelling pressure of undisturbed as well as remolded soils from given geotechnical parameters su...
