Abstract: Engineering geological characterization, subject to spatial variability of soil properties, is a three-dimensional (3D) problem in reality, although it is often simplified as one- or two-dimensional. Direct characterization ...

Abstract: This paper compiles a database consisting of 16 tunnel excavation projects in clayey soils using the earth pressure balance (EPB) tunneling method. Statistical analysis of the data is performed and the probability distributions ...

Abstract: Abstract. In the second stage of ultra-high-pressure ethylene compressors, operation pressures can reach up to 250 MPa, often resulting in wear failure of the plunger–packing friction pair. The conventional mixed ...
