Question

The fine grained cohesive soils can be stabilised by ______

(a) well point system

(b) ditches and sumps

(c) vacuum method

(d) electro-osmosis method

I had been asked this question by my school teacher while I was bunking the class.

The above asked question is from Drainage and Dewatering topic in chapter Drainage and Dewatering of Geotechnical Engineering I

Answer 1

The correct answer is (d) electro-osmosis method

The best I can explain: The vacuum method is suitable for dewatering of fine non cohesive soils, but the electro-osmosis method is suitable for fine grained cohesive soils. The ditches and sumps are used for coarse grained soils.
