# Ground Response and Seismic Slope Stability - Coursework Example

## Extract of sampleGround Response and Seismic Slope Stability

In this report, two parts are considered. In the first part, a ground response analysis for two sites is run while the second part proposes possible design accelerations on basis of the analysis in designing of an embankment structure that will support the proposed roadway. Both of the proposed sites are located in Jamaica. With regard to ground response analysis, edushake analysis program is made use and the results obtained are as displayed in the various tables displayed throughout this report. The input data used are as provided in the coursework materials while the thickness is obtained through calculation of the difference between the depths. A table from the web forms the basis of assumptions made with regard to respective soil’s unit weight. Each soil type has its respective stress (??), pore pressure (u) as well as effective stress (??’) associated with it (Bhandari and Sharma, 2001). Two equations, one for sand and the second one for clay are used in in calculation of maximum shear stress based on the literature from the book of Steven Kramer’s. ...
Width of crest: 15m Height of embankment: 11m Traffic loading surcharge: 15kPa Design PHA (horizontal acceleration): 0.3500g from the ground response analysis 0.3500g from the ground response analysis 0 The embankment is designed using a 1.56 safety factor to facilitate long term and short term stability. With the help of STB2010, the embankment’s parameters were generated using the ordinary method of slices also referred to as Fellenius method for static and seismic stability analysis. The necessary soil characteristics are provided in the table below: Drained strength with strength parameters: c’=0kPa and ф=25? Unit weight of water: ?w = 9.81kN/m2 Undrained strength: c’=85kPa Unit weight of placed material: ? = 20kN/m2 It should be noted that the water table is located at the toe of the embankment. All the assumptions and calculations for the design of the embankment are shown from the Figure 3.1 to the next page. The data as provided in the spreadsheet is as shown below: Basing the divisions on four slices, the ordinary method of slices for design of embankments for drained as well as undrained soil is used. The initial embankment was generated based on the six slices. Consequently, an angle (?) was established in the middle of each slice at the horizontal’s base after which sin (?) and cos (?) were obtained. The equation given below was used in evaluation of the length of each individual slice: The height was measured from the middle of each slice. Additionally, the height (hw) was measured from the middle base of each slice to the point of the water table after which the pore pressure at the base of the slice base was calculated based ...Show more

## Summary

Ground response analysis Name: Institution: Date: Ground response analysis Analysis of local site response is a fundamental aspect of geotechnical earthquake engineering. This is due to its ability to facilitate incorporation of properties linked to sub-surface materials alongside topographical aspects in prediction of the amplitude, content of frequency, as well as ground motion surface duration as a result of specific ‘bedrock excitation’ input…

According to designers, the infill walls are categorized as nonstructural elements with the frames referred to as conventional frames.
