PREDICTION OF GEOLOGY FOR TUNNEL DESIGN AND CONSTRUCTION

GEOLOGY DETERMINES THE SITE AND THE COST OR FEASIBILITY OF A TUNNEL. IF THE GEOLOGICAL PREDICTIONS, BASED ON THE PHYSICAL CHARACTERISTICS OF THE MATERIAL, ARE ACCURATE, THEN AN ESTIMATE OF THE COST WILL BE CLOSER TO THE TRUE COST OF THE TUNNEL. THE GEOLOGIC MATERIALS IN WHICH TUNNELS ARE CONSTRUCTED CAN BE BROADLY CLASSIFIED AS UNCONSOLIDATED AND CONSOLIDATED. THE LATTER CLASSIFICATION IS EMPHASIZED AS DIRECTLY AFFECTING TUNNEL DESIGN AND CONSTRUCTION: THE TYPES OF GEOLOGIC DATA ARE DIVIDED INTO ROCK TYPE AND STRUCTURE. OF THESE TWO TYPES, THE STRUCTURAL DATA ARE MORE IMPORTANT IN THAT THE BEHAVIOR OF THE ROCK UNDER STRESS CAN BE DETERMINED. A BRIEF DISCUSSION IS PRESENTED ON THE COST-EFFECTIVENESS AND INTERPRETATION VERSUS GEOPHYSICAL INVESTIGATIONS AND TRENCHING OR CORE DRILLING.
