Regression Analysis of Initial Geostress Field for Deep-Buried Tunnel of Water Resources Allocation Project in Guangdong Province around the Beibu Gulf by DAI Zhikun, ZHENG Xiao, YOU Siqin

“…Geostress has important influence on the surrounding rock of the deep-buried tunnel during its construction.Accurately identifying the initial geostress of the engineering area can effectively guide the design and construction of the tunnel.In order to study the distribution of initial geostress in the deeply buried tunnel area of water resources allocation project in Guangdong Province around the Beibu Gulf,a three-dimensional geological model was established via the finite difference software FLAC^3D,by reference to the geoengineering conditions and measured data on geostress,with the relevant analysis and calculation conducted under the separate effects of each factor concerning the initial geostress field.And the a multiple regression model between measured and calculated values was established to work out the optimal regression coefficient through multiple regression analysis,thus obtaining the regression equation of geostress.By comparing the regression values and the measured values,it is found that the magnitude and direction of the two values are close to each other,indicating that the initial geostress field established by regression analysis is reasonable and can provide effective basic data for subsequent evaluation of the stability of surrounding rock of the tunnel,support design and long-term safety evaluation and prediction.…”

Research Progress and Prospect of Extreme Water Increase by Storm Surge in Estuaries — A Case Study of Guangdong-Hong Kong-Macao Greater Bay Area by LIU Yuexuan, LI Huijing, LI Lanbin, LIU Xiaojian

“…Significant increases in water and extreme tide levels caused by typhoon storm surges are the primary threat to flood safety in estuarine areas,and are also the main cause of major natural disaster losses in the Guangdong-Hong Kong-Macao Greater Bay Area in recent years.This paper reveals the evolution patterns of water increase in storm surges over the years and introduces corresponding research methods.Meanwhile,it systematically reviews research achievements on the formation mechanism of extreme tide levels in storm surges from both foreign and domestic perspectives.Combined calculation models of extreme tide levels formed by astronomical tides and storm surges in China and abroad are also summarized,with a focus on achievements in dynamic mechanisms during extreme water increase in storm surges.Additionally,a two-dimensional nested mathematical model of storm surges in the South China Sea and the Pearl River Estuary is built,and the most unfavorable typhoon intensity and path are designed.The maximum water increase distribution in the Guangdong-Hong Kong-Macao Greater Bay Area is preliminarily simulated and obtained.Finally,it is urgent to put forward a set of safe,concise,and applicable formula for calculating the extreme tide levels of storm surges as soon as possible based on the understanding of the physical mechanism of the interaction between astronomical tides and storm surges.…”
