Unsaturated lateritic soils are complex to work with due moisture effects. So, the determination of its properties requires lots time, labor and equipment. For this reason, application evolutionary learning techniques has been adopted overcome these complexities. Lateritic soil under unsaturated condition classified as poorly graded A-7–6 group was subjected treatment by using hybrid cement nanostructured quarry fines in a stabilization method. The clay activity, content frictional angle...
Artificial neural network (ANN), gray-wolf, and moth-flame optimization (GWO MFO) techniques have been used in this research work to predict the effect of activated sawdust ash (ASDA) on crack width (CW), linear shrinkage (LS), volumetric (VS) a black cotton soil utilized as subgrade material. Problematic soils or are not good pavement foundation materials except that they pretreated order meet basic strength characteristics required for roads Nigeria. Due reason, there has ongoing evaluate...
Earth Pressure Balance (EPB) Tunnel Boring Machines (TBMs) are more popular in urban mechanized tunneling nowadays. For improving the performance of these machines, time planning, maintenance scheduling and cost control tunneling, tunnel boring machines should be reliable maintained effectively efficiently. this aim, paper seeks to study reliability, availability maintainability hydraulic system EBP-TBM Tabriz metro Iran. The failure repair data were collected during about 26 months machine...
The high boring capability of full-face tunnel machines, especially in urban tunnels, has led to their increased use excavation various and unfavourable geological conditions. Therefore, many efforts have been made predict improve the performance these machines. In this regard, most previous studies focused on effect mechanical properties rock or soil. However, delays due maintenance repair which contribute a major share unwanted unpredicted stops at work, not considered. Reliability...
Earth pressure balance tunnel boring machines (EPB - TBMs) are favorably used in construction of tunnels urban areas. These more expensive with high operational costs require an exclusive study and knowledge on these machine components subsystems their failure downtimes for time planning, cost control performance prediction a accuracy. Thus guidelines reliability, availability maintainability (RAM) analysis EPB completely expressed. Gathering recording all daily repair times other...
