Reinforced Soil Beds on Weak Soils

Abstract

Changing a layer of weak soil in deformed foundation with a compacted soil bed consisted of various strong materials (sand, gravel, pebble-gravel, production waste materials). Existing calculation methods and techniques to build compacted soil beds based on weak highly compressive soils do not meet up-to-date requirements. Calculation methods used the dimensions of compacted beds quite often appear to be overestimated, and this results in increase in costs and working hours needed to build artificial foundation. The paper presents the possibility of using reinforced soil beds as an efficient method to build artificial foundation based on weak soils.

Forecast Jointed Rock Mass Compressive Strength Using a Numerical Model

“…The results obtained in this study have a good match convergence with experimental results 17. The experimental results show that the structural defects have such as discontinuities in the rock mass has a significant impact on the value of the strength and deformation characteristics of the jointed rock mass and strength, and deformation characteristics depend on the direction of the load in relation to major system of discontinuities [20][21][22][23][24][25][26]. …”

Measures of struggle against appearance of cracks in earth dams

“…The weak point of the dam is a seam conjugation with the base kernel. However, the filtration resistance of the seam can be significantly enhanced if the kernel into the bottom section divided groove [3] filled with drainage fine-grained material into several branches, each of which independently interfaces with base [2].…”

“…The application in earth dam the nucleus of dome shape [1] (Fig. 1.a) are reduce the negative impact of "suspension" nucleus and increase the level of its compressive stresses [2]. In this case, the core is been performed with a double curvature (in the form of sickle or bow) in cross section and in plan view.…”

The Different Methods of Displacement Monitoring at Loading Tests of Bridges or Different Structures

“…What method will be used according to the terms of structures, provided accuracy, planned developments, courts around the structure, external conditions, the number of staff. Displacement measurements usually performed using methods and leveling at higher and higher buildings this method more we can give you results, so we have to use any other surveying method (trigonometry, GPS, photogrammetry ....) or nongeodetic method (measuring inductive the senses, the senses of voltage ...) [19,20] To know which method we should use to know the characteristics of the structure, ie. construction height, length range, which is under construction, scheduled shifts ... At the Faculty of Civil Engineering, Transportation Engineering and Architecture, University of Maribor we are sample surveys of bridges and viaducts from 2003.…”
