Engineering Geology Exploration Report
Abstract
The purpose of this report is to:- To study the geology, topography, and climate data at the site of exploration; To explore the stability of the environment, as well as assess the economic value of the exploration site; To provide information on engineering geology exploration so that future construction projects can be correctly planned and implemented.
Introduction
This report was ordered by the World Bank and sponsored by the Chinese Academy of Geological Sciences. It is the purpose of this assignment to provide a comprehensive engineering geology exploration of a site located at the southern border of China. The report provides a detailed overview of the geology, topography, and meteorological conditions at the site, which will allow for the significant hazards of building from natural and man-made events to be accounted for and prevented. The final report will provide information on potential engineering design solutions for construction in a suitable environment. Additionally, the report evaluates the economic prospects of the locality, which may assist builders and investors in their decision-making process.
Geological Exploration
The geological survey consists of investigations into the geological nature of the local environment, and geological engineering and geological use of the area. Examination of geological data acquired from the site revealed the following key findings:
Stratigraphy: The site is located on the South-Eastern edge of the Sichuan Basin, a sub-basin which is part of the Yangtze River system. The stratigraphy of the region consists of seven distinct surface-bedrock sequences, which are composed largely of igneous, sedimentary, and metamorphic rocks. These rock types display different characteristics, and will be examined further in this report.
Structure: Total estimates of displacement along North-South and East-West Structural lines show moderate faulting and folding over the site, indicating that this area is to some degree tectonically active.
Hydrology: The site is situated on the Upper Yangtze River, near the northern part of the river. The river has deep, extensive channels, and the water flows relatively swiftly. There are also seasonal variations in the water depth, and flooding is common during the rainy season.
Climate: This area is situated in an area classified as humid subtropical, with four distinct seasons. Temperature variation is moderate, with hot summers and cold winters. Average rainfall is particularly high during the summer months.
Soils: The area is generally composed of clay soils, with occasional sand accumulations. The texture of the soils is generally poor, and permeability is low.
Environmental Stability and Economic Value
Given the wide range of data and estimated parameters, a general assessment of the stability and economic potential of the area can be made. The stratigraphy, structure, hydrology, and climate variables imply that the region is relatively stable, as no outstanding dangers which could significantly increase the likelihood of landslides, floods, and other natural hazards have been identified. In addition, the soil types present in the area are generally suitable for construction purposes.
However, when considering the economic potential of the area, it is crucial to consider the regional industrial development and population density levels. The area is largely undeveloped, and has limited population density, meaning that investment opportunities in the area are currently limited. On the other hand, land prices are currently low in the region, and the future development of the area could potentially lead to increased economic prospects. Thus, the site is worth further examination, as long-term investment in the region could benefit from this exploration.
Conclusion
The geological exploration report provides a detailed overview of the geological, topographical, and meteorological conditions of the exploration site, located at the southern border of China. This report has examined the stratigraphy, structure, hydrology, and climate variables of the region and concluded that the site is relatively stable and could be suitable for construction purposes. The report has also noted that, given the current economic circumstances, long-term investment in the area remains a viable option. Further exploration and analysis of the region is recommended.
