Discuss the importance of establishing a robust geotechnical monitoring plan before excavation begins, and how it informs construction decisions. (5 marks)
Back
Early Detection of Ground Behavior
- Importance: A well-established geotechnical monitoring plan provides early insight into how the ground will respond to excavation, enabling the detection of potential risks such as settlement, groundwater fluctuations, or stress changes.
- Impact on Construction Decisions: Real-time monitoring data informs immediate adjustments to support systems, excavation rates, or dewatering strategies, reducing the risk of collapse or excessive deformation.
Guiding Excavation and Support Design
- Importance: Monitoring data allows engineers to validate design assumptions about soil and rock behavior, ensuring that excavation and support strategies remain appropriate as work progresses.
- Impact on Construction Decisions: If ground conditions differ from expectations, the monitoring plan enables quick adjustments, such as reinforcing support systems or altering tunnel lining specifications, to maintain stability.
Establishing a Baseline for Risk Management
- Importance: Baseline readings from the monitoring plan allow for comparative analysis, making it easier to detect anomalies and respond to emerging risks promptly.
- Impact on Construction Decisions: With accurate baseline data, project teams can quickly identify and mitigate deviations, ensuring safety and compliance with design criteria.
