Assessment of rapid impact compaction in ground improvement from in-situ testing

Journal of Central South University 2013年第3期20卷 786-790页

作者： m.m.mohammed H.Roslan S.firas Department of Civil Engineering Faculty of EngineeringUniversity of MalayaKuala Lumpur 50603Malaysia

Ground improvement has been used on many construction sites to densify granular materials, in other word, to improve soil properties and reduce potential settlement. This work presents a case study of ground improvement using rapid impact compaction （RIC）. The research site comprises the construction of workshop and depots as part of railway development project at Batu Gajah-Ipoh, malaysia. In-situ testing results show that the subsurface soil comprises mainly of sand and silty sand through the investigated depth extended to 10 m. Groundwater is approximately 0.5 m below the ground surface. Evaluation of improvement was based on the results of pre- and post-improvement cone penetration test （CPT）. Interpretation software has been used to infer soil properties. Load test was conducted to estimate soil settlement. It is found that the technique succeeds in improving soil properties namely the relative density increases from 45% to 70%, the friction angle of soil is increased by an average of 3°, and the soil settlement is reduced by 50%： The technique succeeds in improving soil properties to approximately 5.0 m in depth depending on soil uniformity with depth.

作者： meryem Jemli fatma Karray firas feki Slim Loukil Najla mhiri fathi Aloui Sami Sayadi Laboratoire des Bioprocedes Environnementaux Pole d'Excellence Régional(PERAUF)Centre de Biotechnologie de SfaxUniversite de Sfax

The present work presents a study of the biological treatment of fish processing wastewa at salt concentration of 55 g/L. Wastewater was treated by both continuous stirred-ta reactor（CSTR） and membrane bioreactor（mBR） during 50 and 100 days, respectively. Th biological processes involved salt-tolerant bacteria from natural hypersaline environme at different organic loading rates（OLRs）. The phylogenetic analysis of the correspond excised DGGE bands has demonstrated that the taxonomic affiliation of the most domin species includes Halomonadaceae and flavobacteriaceae families of the Proteobacteria（Gamm proteobacteria class） and the Bacteroidetes phyla, respectively. The results of mBR w better than those of CSTR in the removal of total organic carbon with efficiencies from 97 to 98.6%. Nevertheless, salinity with increasing OLR aggravates fouling that requires m cleaning for a membrane in mBR while leads to deterioration of sludge settleability a effluent quality in CSTR.
