Seawater intrusion into onshore aquifers represents a significant environmental threat worldwide especially in this new era of climate change and sea water rise. This is the case at Zhoushan Islands located Hangzhou Bay (China). Precise monitoring position boundary between freshwater saltwater utmost importance for resource management fractured bedrock. We use Transient ElectroMagnetic (TEM) method to locate salt plume an area where two sets faults-oriented NW-SE NE-SW are connected...
To efficiently link the continuum mechanics for rocks with structural statistics of rock masses, a theoretical and methodological system called statistical masses (SMRM) was developed in past three decades. In SMRM, equivalent models stress–strain relationship, strength failure probability jointed were established, which based on geometric characterising mass structure. This follows physics, mechanics, fracture weakest hypothesis. A general constitutive model complete under compressive shear...
Submarine landslides have attracted widespread attention, with the continuous development of ocean engineering. Due to recent developments in-situ investigation and modelling techniques submarine landslides, significant improvements were achieved in evolution studies on landslides. The general characteristics typical world are analyzed. Based this, three stages landslide disaster proposed, namely, slope instability stage, large deformation movement stage deposition. Given these stages,...
Drilling speed and associated analyses from factual field data of hydraulic rotary drilling have not been fully utilized. The paper provides the reference comparison for utilization information two adjacent vertical drillholes that were formed with same machine bit. analysis original is presented to obtain constant during net process. According along drillholes, digitalization results respectively include 461 linear zones 210 their speeds parameters. can accurately present spatial...
A rapid and accurate prediction of a landslide dam's life span is significant importance for emergency geological treatment. However, current models the state dam are based solely on geomorphological indexes, do not take into consideration attribute properties such as types, trigger factors, types. This study investigates relationships between geometry capacity barrier lake proposes fitting models, which supplement database. Subsequently, six predictive established, utilizing machine...
Monopile foundations are extensively utilized in the rapidly expanding offshore wind power industry, and stability of these has become a crucial factor for ensuring safety projects. Such subjected to myriad complex environmental loads during their operational lifespan. Whilst current research predominantly concentrates on effects wind, wave, monopile extreme environments, it is imperative consider potential influence unexpected submarine landslide loads. In this study, we provide...
Under the influence of long-term external and internal dynamic conditions such as waves, tides, earthquakes, coastal rock masses may slide along unfavorable structural planes, leading to landslide disasters. These events pose threats offshore engineering facilities, tourism, economic production safety. To elucidate impact wave loading on stability rocky slopes, this paper first establishes a generalized geological model computational mechanics slopes. Using fluid dynamics programs, study...
Numerical analysis of the total energy release surrounding rocks excavated by drill-and-blast (D&B) method and tunnel boring machine (TBM) is presented in paper. The stability deep tunnels during excavation terms also discussed. simulation results reveal that blasting a dynamic process. An intense effect captured at large footage. magnitude full-face with D&B higher than TBM under same conditions. rate (ERR) speed (ERS) have similar trends. Therefore, rockbursts are frequently encountered...
Abstract Retrogressive slope failure is ubiquitous in regions of abundant sensitive clays with its mechanism yet to be understood comprehensively. This study gives numerical investigations retrogressive a focus on the 1994 Sainte-Monique slide, Quebec, using large deformation finite element method. Failure mechanisms and post-failure behaviours including global kinematics retrogression distance are highlighted controlling factors discussed parametric studies. Key features slide reproduced...
Abstract The microseism induced by hydraulic fracturing is of great significance to the development geothermal reservoirs and site selection systems. In this study, taking field data from Qiabuqia as a geological reference, several models are developed for simulations based on included in commercial FracMan™ software suit. A series numerical carried out explore effects different fracture parameters, including existence faults, in-situ stress state, occurrence, distribution near microseisms....
The natural structure of columnar jointed rock mass (CJRM) is complex because it was formed during the cooling process volcanic rock. In CJRM, both structures columns and joints are oriented, exact mechanical properties difficult to obtain due lack testing samples that correspond masses. Therefore, this brings challenges for underground engineering construction related CJRM. reconstruction CJRM an effective method can be used resolve problem. However, using artificial means consider detail...
In offshore engineering, marine clays, which are widespread in the southeastern coastal areas of China, may be subjected to two-way cyclic stresses. To experimentally investigate effects stress with low-stress amplitude on behavior soft clay, a series triaxial tests is performed intact clay from Zhoushan covering various values ratio (CSR) and confining pressure (p′0). Several useful conclusions inferred: First, double-amplitude axial strain (εDA), dynamic modulus (E), energy dissipation (W)...
