Identification of Cameroon's geological structures through a gravity separation and using seismic crustal models

, 2021
Residual gravity data provide useful information for a geophysical interpretation of geological sources. Several techniques have been developed and applied to separate a different content in gravity data.

Effects of geological structures on rainfall‐runoff responses in headwater catchments in a sedimentary rock mountain

Hydrological Processes, 2020
Clarifying rainfall‐runoff responses in mountainous areas is essential for disaster prediction as well as water resource management. Although runoff is considered to be significantly affected by topography, some previous studies have reported that ...

An application of CSAMT for detecting weak geological structures near the deeply buried long tunnel of the Shijiazhuang-Taiyuan passenger railway line in the Taihang Mountains

, 2020
The Shijiazhuang-Taiyuan (ShiTai) high-speed railway line is designed to cross the Taihang Mountains. The line will include the construction of a 27.85 km long tunnel with a maximum depth of 450 m. The Taihang Mountain Tunnel is the key to the successful

Modeling of magnetic anomalies generated by simple geological structures through Genetic-Price inversion algorithm

, 2020
A new approach to the interpretation of magnetic anomalies generated by geological structures resembling simple geometrical bodies is presented. The method is based on the Genetic-Price hybrid Algorithm (GPA) recently proposed by the authors for the ...

Evaluating some dynamic aspects of TBMs performance in uncertain complex geological structures

, 2020
The complex and uncertain geological structures may cause difficult prediction for dynamic performance of tunnel boring machines (TBMs). The dynamic model of the thrusting and supporting system of TBM is established, in which the uncertain loads from ...

Geological structures controlling the placement and geometry of heat sources within the Menengai geothermal field, Kenya as evidenced by gravity study

Geothermics, 2019
Menengai volcano is one of the late Quaternary caldera volcanoes formed on a massive shield in the inner-trough of the Kenya rift valley, associated with a high thermal gradient resulting from shallow magmatic intrusion.

An experimental testing apparatus for study of suffusion of granular soils in geological structures

Tunnelling and Underground Space Technology, 2018
This study mainly focuses on the suffusion process of granular soils, especially that filled in geological structures, such as faults and karst conduits.

The spectral element method: An efficient tool to simulate the seismic response of 2D and 3D geological structures

Bulletin of The Seismological Society of America (BSSA), 1998
We present the spectral element method to simulate elastic-wave propagation in realistic geological structures involving complieated free-surface topography and material interfaces for two- and three-dimensional geometries.
