Geological engineers have mostly been involved in geotechnical problems since the beginning of 19 century. Engineering geological maps and field data are needed to solve these problems. The amount of data for these maps is extremely large, so putting all the map elements on the map sheet causes difficulties while solving problems. The magic words, Geographic Information System (GIS) is a tool f...

The Konjsko tunnel is an integral part of the Zagreb-Split-Dubrovnik highway, section Prgomet-Dugopolje. It consists of two tunnel tubes having 1326.0 and 1133.8 meters in length. The greatest overburden amounts to 150 m. This paper presents geotechnical measurement results and back numerical analyses. Back numerical analyses in combination with geotechnical measurements enable safer and more r...

在岩土工程领域, 许多应用都涉及到多尺度和多物理场, 例如内部侵蚀、水力压裂、能源桩、城市垃圾处理、非常规油气藏的生产、天然气水合物的热激法和降压法开采、路面的冻融循环、放射性废物处理、污染物运移和二氧化碳封存等等。在文献中, 这些多物理场通常可能包括以下两个或者两个以上方面: 固体变形、流体流动扩散、热传导和热对流、化学/生物反应、电场等等。此外, 所研究的空间尺度可以从纳米级到微米级到数百公里级, 时间尺度也可以从纳秒到数百或数千年不等。近些年来, 受益于计算能力的持续发展和对精密设备制造的大量投资, 数值模拟和多尺度实验室测试已成为地质力学及其相关领域的主流方法。科学家们为了求解多尺度和多物理场过程, 已经开发并成功应用了不同的本构理论、控制方程模型、数值离散方法、求解器等等。为此, 本专题收集在该研究领域具有代表性的研究成果, 涵盖用计算流体动力学和离散元法进行多层土的潜蚀模...

The simulation of structural and geotechnical systems is a critical step in their design and assessment. The purpose of an earthquake simulation is to estimate the performance of the system under seismic excitation or loads that represent the effects of an earthquake. Structural and geotechnical simulation has a long history of development in earthquake engineering. The computation required to ...

reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. in this regard, this research deals with development of a 3d geological engineering model on mashhad city soil using sequential gaussian simulation (sgs) approach. the intense variability of soil in the study area has sometimes caused serious problems in civil engi...

Through coming into force of the Concrete Construction Technical Regulations [1], to the European standards were also added [2] and [3] (Attachment I.4, Standards) in civil engineering, i.e. construction and geotechnical regulations. Based on this, a need appeared for revising current technical regulations [4] and critical view of new standards. A certain number of comparable analyses on as lar...
