“…Urbanization followed by economic advancement place a considerable burden on the available land resources to meet the innumerable needs of urban centers. However, in recent years, the concept of artificial islands has been widely being used for housing, commercial, industrial purposes, trade, tourism, and strategic motives to manage the inevitable increase of urban space volumes [40]. These mega coastal projects will threaten the existing marine ecosystems if appropriate measures are not considered intently [41].…”

Artificial island development (AID) to tackle rampant urbanization on scarce land puts all marine biodiversity at huge risk and is recognized as a global conservation issue worldwide. This study critically reviews the gaps that undermined biodiversity and ecology during construction activities of the artificial islands in the Gulf region that could be alleviated if apposite environmental values and sustainable strategies of different regions of the world had paid enough heed to economic and social aspects. The method used for this study was an analytical descriptive literature survey, and the resources were chosen after three phases of quality assessment. This survey found various barricades to sustainable AID, such as lack of scientific data, adequate site selection, ineffective environmental evaluations, noncompliance with legislation, and economic gains over the environmental aspects. It was concluded that to protect the marine ecosystem from inevitable degradation, strict compliance with international and national legislation, research and baseline data collection, strengthening of the existing environmental assessment, continuous capacity building, and modern practices of different countries should be brought to the forefront. Furthermore, this study aims to provide guidance to policymakers and governmental organizations to mitigate emerging environmental issues during AID through strategic decision-making processes.

“…During the construction of the Sydney Metro Metro in Australia, the shield machine failed to respond to the stratum change in time during the excavation process, which led to the rapid drying of the slurry and the continuous shrinkage of the soil around the tunnel, which eventually led to ground collapse and damage to many houses (Han and Ma, 2020).…”

Due to the characteristics of soft soil, ground settlement is highly prone to occur in the construction process, and ground loss is one of the essential factors causing ground settlement in shield tunneling. This study calculates the ground loss rate of some shielded soft-soil sections in the Hangzhou area using Peck’s back analysis method. It examines the influences of the geological parameters and the geometric parameters of a tunnel on the ground loss rate through data analysis to develop a model for predicting the ground loss rate in soft-soil areas. Then the model for predicting the ground loss rate based on eXtreme Gradient Boosting (XGBoost) and Bayesian optimization is established, and the prediction method of the ground loss rate, combining the surface settlement value, detailed geological parameters, the geometric parameters of the tunnel, and construction parameters, is innovatively proposed. The results show that the soil properties and the grouting factors of the excavation face affect the duration of the instantaneous settlement of the ground surface. There is a specific correlation between the depth-to-diameter ratio, the coefficient of variation in the advancing speed of the shield machine, the maximum surface subsidence, and the ground loss rate. The prediction model of the ground loss rate based on the synergistic approach of Peck back analysis and eXtreme Gradient Boosting and Bayesian optimization has high reliability in soft-soil layers, and this method can provide a specific reference for predicting construction risk in related projects.
