Artificial intelligence (AI) algorithms of adaptive neuro-fuzzy inference system or the network-based fuzzy (ANFIS) has been deployed to predict swelling potential (SP) treated weak soil. The soil was with quicklime activated rice husk ash (QARHA) and prediction efficiency compared previous outcomes this operation from literature. need for effective utilization construction materials achieve su...

Although forest road networks are an important infrastructure for forestry, recreation, and sustainable management, they have a considerable effect on the environment. Therefore, detailed analysis of various benefits associated costs network construction is needed. The cost earthwork in can be estimated based change topography before after construction. However, accurate estimation volume may n...

The soil water retention curve (SWRC) or soil–water characteristic (SWCC) is a fundamental feature of unsaturated that simply shows the relationship between suction and content (in terms degree saturation volumetric gravimetric content). In this study, applications SWRC SWCC have been extensively reviewed, taking about 403 previously published research studies into consideration. This was achie...

In civil engineering and building construction, the earthwork volume calculation is one of most important factors in design construction stages; therefore, an accurate necessary. Moreover, because managing earthworks highly important, this study, a three-dimensional (3D) model for management was performed using unmanned aerial vehicle (UAV) RGB camera. Vertical high-oblique images (45°, 60°, 75...

Mine development requires continuous management because it causes rapid topographic changes and environmental damage. Drones can be used to produce three-dimensional spatial information by quickly accurately photographing areas that are difficult or dangerous for humans approach. In this study, we investigated the possibility of using drone photogrammetry determining recovery in mines. The accu...

Purpose: Analysis of the problem choosing optimal set machines in building transport construction facilities. The equipment rational combination choice earthmoving sets is always relevant. Construction process productivity, time, labor costs, production costs and many other indicators efficiency depend on how rationally chosen machine sets. Methods: calculation formulas reliability theory, theo...

In Pakistan, many subsurface (SS) drainage projects were launched by the Salinity Control and Reclamation Project (SCARP) to deal with twin problems (waterlogging salinity). some cases, sump pumps installed for disposal of SS effluent into surface channels. Presently, have become dysfunctional due social financial constraints. This study evaluates alternate design Paharang system that could per...
