15.48.390 Soil/geologic investigation report.

As soil or geological survey report may be applied to the applicable website, it is necessary to include all of the following.

Site map showing the topographic features of the site and the location of all soil drilling and test excavations.

C. Assessment of soil type classification (unified soil classification), relevant laboratory test data, and subsequent assessment of existing soil properties, distribution and strength.

D. Description of the geology of the premises related to the site and the geology of the adjacent area.

H. Record the record of each soil's bore record and test drilling and show the ground level and depth of each soil or rock layer.

I. Evaluate the stability of the relevant native slope and make recommendations on the largest cuttings and embankment slopes of the proposed project.

K. Recommendations on grading procedures and specifications, including mining methods and subsequent filling methods.

Preliminary geological survey is necessary to complete shallow underground survey using backhoe or hand drill which characterizes shallow strata, soil mechanical properties of the underlying geological material, hydrological conditions of groundwater, and geographical location Including other geological attributes. A field survey of the design premises and surrounding areas involves traversing a valley of about 1 mile and 1 mile from the site. Crossing should include studies on slopes, tributary valleys, landslides (active and inactive), faults, spring and infiltration, counterbored, bare rock profiles, and unconsolidated coating properties. Surveys of slopes of highlands and valleys can provide clues to thickness and thickness

Geological descriptions of surface surveys and underground investigations, laboratory tests, and geological engineering reports provide reliable information on all geological conditions that may affect the design, construction and cost of the project Should be comprehensive enough to do. Geotechnical reports should consider the history of earthquakes in the area unless another earthquake report is required. Geological sections and sections should show important features such as correlation between soil and rock units, as well as water level, moisture loss, faults, shear zone, blades, connections and melting zone. In these sections you need to emphasize the strata and show the depths of primary and secondary weathering. All the cross-sectional and cross-sectional views must be superimposed on the main structural profile of the existing or proposed structure and the foundation excavation depth.

Geological site survey and soil mechanics testing provide sufficient detail and strength to protect the planning, design and implementation of engineering approaches. Therefore, the procedure and intensity of the survey, and the type of sample used depend on the location and specific purpose or structure. Geological surveys can also be accomplished using remote sensing techniques or other non-invasive methods that characterize the quality characteristics of on-site earth matter. In addition, because the topography, land use, and other geoscientific information are provided in digital form, you can analyze the situation of geological sites highly.
