How does the presence of groundwater affect earthwork?

The correct answer highlights the significant impact that groundwater has on earthwork processes. Groundwater can greatly influence soil stability, particularly during excavation and compaction activities. When groundwater is present, it increases the soil's moisture content, which can lead to a reduction in soil strength and cohesion. This decrease in stability may cause issues such as soil collapse or sloughing of excavation walls, making it difficult for operators to safely carry out their work.

Additionally, excess water in the soil can lead to the formation of mud, which complicates equipment operations and prevents effective compaction. Proper management of groundwater is essential in earthwork projects to ensure safety and the integrity of the constructed elements. The presence of water necessitates careful planning and execution, including measures for drainage or dewatering, to achieve optimal results in excavation and compaction processes. This underscores the importance of considering groundwater in earthwork operations.
