Ga_Svm_Adaboost Model For Prediction Of Earthquake-Induced Sandy Soil Liquefaction, Mao Zhiyong, Huang Chunjuan, Lu Shichang

Coal Geology & Exploration

In order to predict the liquefaction of sand, the seismic intensity, groundwater level, covering thickness, standard number, average particle size, landform, soil quality and inhomogeneity coefficient are selected as influencing factors. Genetic algorithm(GA) is used to optimize the parameters of support vector machine(SVM) by using correlation analysis and factor analysis model, and combining with Adaboost iterative algorithm, the GA_SVM_Adaboost model for predicting the liquefaction of sand is established. 329 sets of survey data of sandy liquefaction site in Tangshan earthquake were used to train the model, and 68 samples of sandy liquefaction data were predicted by using the good model. …

Development Of High Temperature Borehole Inclinometer, Qu Zhaogui, Gong Mingmao, Zhou Ce, Wang Guangzhai

Coal Geology & Exploration

In the detection of high-temperature and high-pressure dry heat rock drilling location trajectory, the instrument has some problems, such as poor performance, poor stability, low measurement accuracy and large energy consumption. A set of high temperature borehole inclining device is designed to solve the problem of high temperature and high pressure measurement deviation and temperature measurement. Adopt high temperature resistant components, design control and measurement circuit. Automatic intermittent power supply is adopted to reduce heat dissipation and power consumption. The design of heat preservation pipe and pressure detection pipe is carried out by using ANSYS finite element software to conduct …

Experimental Study On The Influence Of Well Inclination Angle Of Coalbed Methane Well On The Cementation Strength Of Cement-Formation Interface, Gu Jun, Li Linwei, Sun Dexing

Coal Geology & Exploration

In order to control the problem of water channeling in the process of coalbed methane(CBM) production, based on the self-designed test device and method, the test data of the shear strength at cement-aquiclude interface (CAI) is obtained under the conditions of well inclination of 0°, 30°, 60° and 90°. The mechanism of the influence of inclination angle on the shear strength at CAI is analyzed. The results show that the shear strength at CAI decreases with the increase of the inclination angle. The reason is that as the inclination angle increases, the upper part of the mud cake ring becomes …

Application Of Wire Line Coring Technique In Overburden Drilling, Li Baijun, Zou Run, Guo Chao

Coal Geology & Exploration

In order to improve the drilling efficiency of two oil and gas geological survey wells "Jitaodi 1" and "Ji Bai Di 1" in Baicheng area of Jilin Province, wireline coring technique was applied in overburden drilling. Based on the lithological characteristics of the drilled strata, combined with the technological characteristics of core extraction by lifting the drill pipe and wireline core extraction, by designing the bit, drilling flushing fluid and by improving drilling procedure parameters, drilling tool nozzle flow channel, the wireline coring drilling method has been successfully applied in drilling overburden strata(about 1 100 m thick). Compare with the …

Seamless Lidar Surveys Reveal Rates And Patterns Of Subsidence In The Mississippi River Delta, Celeste E. Woock

LSU New Orleans Theses and Dissertations

Light Detection and Ranging (Lidar) data are used to report the temporal and spatial patterns of subsidence as well as the potential contributors to subsidence within the Barataria and Terrebonne Bays. In recent decades, subsidence in southeast Louisiana has become a topic of substantial and growing concern to the scientific community, the local residents, and all those invested in the region. Lidar data were acquired from the United States Geological Survey (USGS) and the LSU Center for Geoinformatics. The data has been manipulated to map the differenced Lidar, complete an instantaneous slope analysis, and determine the thickness of the Holocene …

An Integrated Resource Plan For Public Service Company Of Colorado (Psco), Rawley Loken, Alex Smith

Master of Science in Energy Systems Management

An Integrated Resource Plan (IRP) is a tool used by load serving entities (LSEs) to plan how they will meet forecasted energy demand and system reliability requirements through a combination of supply-side and demand-side resources. The goal of an IRP is to identify the lowest cost option to meet future load while also adhering to policy requirements. For Public Service Company of Colorado’s (PSCo) IRP process, a suite of generating resources, storage capacity, and demand-side management programs are all considered when developing a plan that meets state and utility regulatory requirements and environmental targets.

In 2016, PSCo’s system peak demand …
