OVERVIEW The Flinders Ranges Council as part of its commitment under its Hazardous Work Policy, recognises its obligation to manage the health and safety risks associated with excavation and trenching carried out as part of Excavation and embankment (cut and fill) Excavation = the removal of soil or rock from its natural location. Embankment = the placement and compaction of layers of earth or rock to form a roadbed of the planned shape, density, and profile grade. Various sections of a roadway design will require bringing in earth. excavation work - If the proposed excavation is more than 1.5 meters deep and a worker is required to enter the excavation, notice must be given to the division not more than 48 hours before the day that that excavation work is scheduled to begin. This notice is achieved by completely filling out and faxing a standard Ex-Fax to the division. Excavation depths exceeding 10 to 20 ft, require specialized planning for support. Lateral earth pressure is proportional to the vertical pressure. As a cut is made, the soil at the face tend to expand and move into the cut area. If a support is placed against the excavation surface to prevent the soil movement, then the pre-excavation This traditional excavation method, also referred to as the skeleton method, is the oldest method used in ecological root research (Hales, 1727; Du Hamel Du Monceau, 1764/65; Thiel, 1870; Hays, 1889; Kraus, 1892—1896; Fruhwirth, 1895; Schultz-Lupitz, 1895; Ballantyne, 1916, and others).

On the other hand, due to the limited space in urban areas parallel to a rapid development, forced the engineers to provide and apply reliable and suitable construction methods. Deep excavations which are supported by walls are common construction methods. Section 1: Excavation and Embankment: This section deals with the removal and/or addition of soil to the existing terrain. Section 2: Borrow Pit Volumes: There is some overlap with the section 1 and this section but this deals with taking soil from an existing location. The soil properties, volumes, and water content Figure 0-1. Excavation of deposition holes using a novel dry blind boring technique demonstrated in the Olkiluoto Research Tunnel (Autio & Kirkkomaki 1996) is currently being planned by Posiva Oy. The selected method to date for the excavation of deposition tunnels is Drill & Blast, but Horizontal Raiseboring has been identified as one possible In the meantime, excavation methods have an important role in slope stability. These methods effect strength reduction factor (SRF) of slope s due to the force induced on rocks. In this paper four slopes with dips of 30, 45, 6
