Distribution of Stresses in Soil - 3 PDH
This course covers the analysis of stress conditions at a point, stresses beneath structures and embankments, and empirical methods for estimating loads on buried pipes, conduits, shafts, and tunnels.
Seepage and Drainage - 7 PDH
This course covers surface erosion, and analysis of flow quantity and groundwater pressures associated with underseepage. Requirements are given for methods of drainage and pressure relief. Control of soil erosion must be considered in all new …
Sanitary Landfills - 3 PDH
This is an introduction to the planning and design of sanitary landfills. You will learn about dry and wet landfills, site selection, site development plans, site layout, trench design, leachate control and treatment, gas control, runoff control, support …
Deep Foundations - 3 PDH
This course will provide you with an introduction to deep foundations. A deep foundation derives its support from competent strata at significant depths below the surface or, alternatively, has a depth to diameter ratio greater than 4. A deep foundation …
Rock Mass Characterization - 3 PDH
This course provides guidance in the description and engineering classification of intact rock and rock masses, the types, applications and analyses of rock property tests, the evaluation of intact rock and rock mass properties, and the selection of …
Engineering Properties of Soil and Rock - 5 PDH
This course will introduce you to the engineering properties of soil and rock. You will learn how the properties of compaction, permeability, consolidation-swell, shear strength, stress-strain modulus (modulus of elasticity), and Poisson’s ratio are …
Settlement and Volume Expansion in Soils -5 PDH
This course concerns (a) immediate settlements, (b) long-term settlements, (c) rate of settlement, (d) criteria for tolerable settlement, (e) methods of reducing or accelerating settlements for saturated fine-grained soils and (f) methods for controlling …
Soil Grouting - 3 PDH
Grouting is a widely used method for strengthening and sealing rock, soil and concrete. The possibilities for sealing structures are of great importance from both an economic and environmental point of view. The cost of grouting has in certain projects …
Earthwork for Foundations - 3 PDH
This course provides an introduction to earthwork for foundations. In general, excavation for subsurface structures will consist of open excavation and shaft and tunnel excavation. Where excavation to great depths is required, a variety of soils and rock …
Dam Arch Foundation Investigation - 3 PDH
Foundation investigations for arch dams generally must be accomplished in more exacting detail than for other dam types because of the critical relationship of the dam to its foundation and to its abutments. This course discusses the procedures which are …
Geotextiles in Pavement and Drainage Applications - 2 PDH
This course will introduce you to geotextiles made from polypropylene, polyester, polyethylene, polyamide (nylon), polyvinylidene chloride, and fiberglass. You will learn about their physical properties, functions, and design methods. You will also learn …
Bearing Capacity Analysis - 3 PDH
This course will introduce you to methods for analysis of soils and rock to determine load bearing capacity. Stresses transmitted by a foundation to underlying soils must not cause bearing-capacity failure or excessive foundation settlement. The design …
Soil Stabilization for Pavements - 3 PDH
This course will introduce you to accepted methods for stabilizing soils underlying new pavements to improve strength and durability. You will also learn about methods to achieve better soil gradation, and reduction of plasticity index or swelling …
Foundations on Fill and Backfilling - 3 PDH
Foundations may be constructed on fills and backfilled material. Fills may include conventional compacted fills; hydraulic fills; and uncontrolled fills of soils or industrial and domestic wastes, such as ashes, slag, chemical wastes, building rubble, and …
