A geotechnical investigation in Worcester typically involves several key components aimed at collecting comprehensive data about the subsurface conditions. This process includes drilling boreholes, excavating test pits, and collecting disturbed and undisturbed soil samples for laboratory testing. A disturbed sample is one in which the natural structure of the soil has been altered during collection, making it suitable for certain laboratory tests but less reliable for assessing in-situ conditions compared to undisturbed samples. Soils in the Worcester region are classified based on factors like particle size, plasticity, and grain shape.
Soil tests such as grain size analysis, direct shear tests, and standard penetration tests are conducted to evaluate soil properties like bearing capacity, strength, and compressibility. The types of tests conducted during the investigation include both field tests and laboratory tests on soil and rock samples to determine engineering properties essential for geotechnical assessment. The properties of soil, such as cohesion, friction angle, and compressibility, directly influence its behavior under load. Laboratory tests on soil samples measure a wide variety of soil properties and can reveal both direct and index properties, providing a comprehensive understanding of soil behavior in Worcester’s unique geological setting.
Additionally, groundwater conditions and groundwater levels are examined to understand their impact on soil stability and foundation performance in Worcester. The laboratory tests performed provide detailed information on soil characteristics, and specific test measures, such as impact acceleration, are used to evaluate soil compaction and other critical properties. The data collected during these investigations form the basis for the geotechnical analysis and the development of a ground model that accurately represents the Worcester site. Groundwater management is essential to mitigate risks related to soil liquefaction and settlement common in the region. The dynamic response of soil can be estimated by measuring its shear wave velocity in geophysical evaluations, which is crucial for understanding soil behavior under dynamic loads in Worcester.
