Articulated Concrete Block Revetment

Articulated Concrete Block Revetment

Articulated Concrete Block Revetment

(OP)
Is anyone aware of design guidance for articulated concrete block revetments, specifically for installation on a slope (i.e. not open channel applications).  I am aware of design using hydraulic stability methods.  However, these methods do not allow the consideration of additional stability provided by mechanical anchoring of the mattress (they essentially look at one block and treat it as a piece of riprap).  Thank you.

RE: Articulated Concrete Block Revetment

Some of these blocks are  anchored together by being poured into a nylon fabic formwork.The mat is laid on a slope and each block compartment is pumped full of concrete or grout. Nylon cables running perpendicular to the mat and sometimes also across the mat can be added to increase strength depends on what is specified and where the blocks are being used. They can also be anchored into the slope by helical piles for example or whatevere is appropriate in the situation. The anchors have to tie into the blocks or nylon cables.As for calculations on stability
varous universities have done some studies( University of Winnepeg I think has some info. The US Core of engineers should have some info in their manuals.
 There are other types of articulated bocks using different link methods so you will need to establish the preferred type of block and what strenghts you need first before you do any stability calculations.
