I appreciate all valuable contributions. Experience is beyond the scope of all books. Being a young geotechnical engineer and working as a researcher I feel like I am a bird lacking one wing. That wing is the experience acquired in the field. The present situation is that I am hired to...

BigH & PEinc thanks for your replies. I am hired to plan a retaining structure (a secant-piled or steel-pile wall) to retain a foundation pit of 90m to 60m having a depth of 20m. The GWL is 6m below ground. I am not sure to propose a dewatering process, though I am quite aware that I have to...

Can anybody help me to find out if I can use a series of soil anchors to retain a 20m wall in a saturated sand medium?

I need to retain the soil for a foundation pit of depth 20m. The soil medium is a homogenous sand (SP-SM) and standart penetration values reach 30 at 10 meters and greater than 50 at 20 meters. The groundwater table is 6 meters from the ground. The routine procedure in Turkey is to use tangent...

In reversing the shearbox most of the disadvantage is the orientation of the shear zone. If it is horizontal there is no problem but if not then a stress accumulation occurs especially on the corners. I may propose dividing the two halves by using a wire saw (to get a smoot flat shear surface)...
