    Ground improvement suggestion on reclamation area

    Eirechch, We have received an offer from one of the vendor proposing peripheral stone column behind the sheet pile wall. Commerically the offer is too high. Also, we have executed tie rod method to retain the sheet pile in our previous project for 30m width using deadweight wall from other end...

    Ground improvement suggestion on reclamation area

    Hello everyone, we are doing the reclamation in one of our projects with an area of 400m x 50m from -2m to +1m. Also, we are treating the reclamation ground with PVD to decrease the future settlement with proloading fill and the height of the fill is 5m above +1.0m to achieve the future...

    Reference for chisel and bailor method against the dynamic impact for piling work.

    Hi, I have found these reference for my thread. Reference are given the attachment. As we all well known for the spacing of pile for construction which listed below 1.IS 2911-part 2/2010 – for socketing pile minimum spacing 2.5D section 6.6 2.IS 14593 -1998 - for rock socketing pile minimum...

    Reference for chisel and bailor method against the dynamic impact for piling work.

    Hello, I am doing the piling work using chisel and bailor method with rigid gantry platform. The gantry has two pile grid with 7.5m length and 15m width. The gantry has 2 A-frame to do chisel the pile simultaneously (Photo is attached for reference). My client has given the NCR to stop the...

    Requesting for Settlement criteria of Minerals Stock Pile

    Oldest Guy - Thanks for your suggestion. In my reclamation yard we have installed settlement platform 1m*1m steel plate at bottom and connected with 3cm pipe to certain elevation to measure the total settlement due to 4.5m height reclamation sand fill on the backyard area. The maximum settlement...

    Requesting for Settlement criteria of Minerals Stock Pile

    To - Oldestguy Thanks for your straight forward reply towards my request. Since there are many consultant and client are just limit their criteria during the tender without having enough Geotechnical information. We have awarded this EPC project by underestimating the ground improvement...

    Requesting for Settlement criteria of Minerals Stock Pile

    Soft clay is situated in the deeper depth. So excavation is not a good solution to limit the settlement. Vinothkumar S Geotechnical Engineer

    Requesting for Settlement criteria of Minerals Stock Pile

    We have taken all consideration including slope stability FS>1.5 in the revetment and other structures. we have calculated the possibility of sliding away the soil between consecutive columns – 2 to 3 m of shear failure zone which is okay in the replacement ratio of Controlled modulus column...

    Requesting for Settlement criteria of Minerals Stock Pile

    To oldestguy - Based on settlement calculation with reference to geotechnical investigation data, we have computed and measured the total settlement will go up to 850mm and it can be restricted upto 300 mm settlement after ground improvement such as CMC with minimum spacing of 2m with 450 mm...

    Lateral pile load test - Deflection measurement

    Hi, We are doing a Lateral pile load test on land pile of dia 1.4m for a marine stimulated condition by considering the dredge level 14.5 m by providing the outer casing dai 1.6m upto the above dredge level. Design load is 10 T and Test load is 20T. We are going to fix two dial gauges, one at...

    chisel Blow count vs rock strength in Pile foundation

    Hi, We are performing insitu pile drilling using winch machine (chisel weight is 3.5ton) in weathered rock strata. Is there any correlation/reference to find out rock strength vs number of chisel blow counts. Thank you. Vinothkumar S Geotechnical Engineer

    Lateral pile load test - Deflection criteria

    If it is so? What is the useful of performing the lateral load test. because i am going to perform the test for container terminal berth. IRC limitation is 1% of the pile diameter. Indian standard 2911 - 50% of the final load at which the total displacement increases to 12mm, final load at...

    Lateral pile load test - Deflection criteria

    SoilRocks (Geotechnical)12 Dec 10 14:07 I don't usually see a structural engineer use a percentage of the pile diameter. Almost 100% of the time, I see them pick an allowable deflection, and apply a factor of safety to the ultimate lateral load that will produce that deflection. The...
