One of the efficient techniques to improve the behavior of the paved road under traffic loads is implementing the geosynthetic material in the sub-base or the soil under the road. In the past years, many researches have been done about this topic, but the study on the effect of soil/load conditions on the performance of the rehabilitated paved road by geogrid in order to investigate the effecti...

This technical note describes a set of direct simple shear (DSS) tests that characterise the evolving geotechnical properties soft soil, through loading history represents episodic load...

This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...

This paper presents a finite element study of the stability and deformation of a cofferdam incorporating bucket foundations in soft clays at Zhuanghai Artificial Island. The development of excess pore pressures in the clays has been investigated in terms of the progress of construction, geometry of structures and hence the load resulted. The effect of prefabricated drains on the behavior of the...

The models that were analyzed using FLAC version 4.0 (FLAC, 2000) are shown on Figure 5.1. The models have different soil types: loose silty sand with 20% fines content (Figures 5.1a and 5.1b), soft clay (Figure 5.1c), and silt (Figure 5.1d). Hence, the determination of the parameters is different for each model. The following sections discuss the determination of the parameters used in the ana...

Chromobacterium violaceum is a gram negative, facultative anaerobic coccobacillus. Human infections are rare and usually occur after exposure to contaminated soil or water. Infections can present with fulminant septicemia, multiple abscesses and rapidly spreading soft tissue infections. Here we present a fatal case of pulmonary Chromobacterium violaceum infection following aspiration of drain w...

At the present stage of reforming housing and public services, toughening requirements for life reliability pipelines municipal support systems, issues developing choosing material type pipes in relation to specific operating conditions urban water supply systems become very relevant. The safety have been main applicable these as most important components health one priorities state social poli...
