3 Develop Preliminary Geologic / Geotech Conceptual Model for the Project Goal is to: identify the primary technical considerations, limitations/constraints, scope, purpose, geotechnical targets, and site conditions that must be resolved.

4 Identify/Collect Available Geotechnical Data in the Project Area Information can include: Geologic maps Data from previous reports Drill hole data Preliminary mapping Bridge or control structure Compile available local data into a database for further evaluation. Roads or Canals Residential Area

5 Field Geologic Mapping

6 Typical Drill Hole Logs General: Drill rate Rig Behavior Circulation return Depth to water Instrumentation Drill difficulties Shift changes Testing intervals and results Soil: Lithology Soil type (USCS) Color Consistency / density Grain size distribution Moisture Cementation Plasticity (clays) Roundness Roughness Code Slickensided Polished Smooth Rough Very Rough Rocks: Rock Type Recovery, RQD, GSI Color Texture Degree of weathering Strength Hardness Structure Discontinuities: o Type o o o o o Width Infilling Amount & Type Surface Shape Roughness Spacing (Joint Sets)

7 Types of Samples Drive Samplers (SPT, MC, LPT) MC Liners Mod Cal SPT Energy Calibration Can be performed in most soil types, difficult in gravel-cobbles. Provides information relating to relative density, strength, and applicability of some ground improvement methods (e.g., soil mixing, jet grouting, chemical grouting)

8 Types of Samples Undisturbed Samples Shelby Tube Pitcher Sampler Piston Sampler Typically applied to soft-medium, stiff cohesive soils in order to test strength, stiffness, consolidation, etc

9 Types of Rigs Solid Stem Some typical methods to drill the subsurface include: Auger Mud/Air Rotary Mud/Air Rotary with Casing Advance Reverse Circulation Sonic Becker Penetration Large Diameter Cone Penetration Tests (CPT) Rock Core Hollow Stem Each of these methods have pros and cons and are well suited for specific exploration programs, depending on both the subsurface conditions as well as the data needs for the program.

10 Typical Drill Hole Logs Rock Log Soil Log

11 Data Compilation Summary Sheets

12 Cone Penetration Test (CPT) Pros: Widely available Efficient No water, mud or air Advance many holes in comparison Cons: No samples Push depth limitations

21 Settlement Ground Surface V S W 2.5i Y Adjacent Structure S MAX i 0.05 S MAX Average Slope = S max / W Z Settlement Influence Line -Y 2 /(2 i 2 ) D = 2R S = V S i 2P

22 Settlement Mechanisms Tunneling operations have inherent risks of settlement from: Excessive overcut Excessive or uncontrolled spoil removal Driving of temporary soil supports Inflow of water in granular soils Mechanisms for Tunnel Settlements

23 Settlement Monitoring Settlement should be controlled by: Designing construction methods to prevent settlement Continued monitoring of surface and subsurface conditions for settlement or indicators Extensometers:

24 Flowing Ground Sinkhole clay wet fine sand wet sand Flowing, running ground silt Flowing Ground in TBM

25 Flowing Ground - Tunnelman s Ground Classification
