Question 3 This saturated clay is considered undrained under these conditions. Because the soil is made of saturated clay this means excess pore water pressure needs a lot more time to dissipate due to the difficulty for water to travel through this type of soil. The building was just recently built so we can assume that the ground under the silo has excess pore water pressure. With the recent rapid loading of the silo, which was twice the weight of the silo, we can say that the ground’s excess water pressure has increased even more. A geotechnical engineer should have been called before the rapid loading took place to test the shear strength of the soil to prevent

Unformatted text preview: structure failure. If shear failure hasnt occurred after the loading of the silo the chance of shear failure in the soil will be decreasing as time goes on until the soil become an undrained soil which means there will be no excess water pressures. During this period of draining the structure is still in threat of shear failure. Environmental changes could occur, which could create, shear failure. So if the structure has not failed an engineer should still be called to evaluate the shear strength of the soil under these conditions and determine if it will possibly fail.
