A ha-ha is (typically?) a retaining wall, so I wouldn't expect the mechanical
advantages to apply in the same way. I imagine it would also complicate the
excavation/infill.

So is it the case that it brings the cost of the wall down from

2N (two brick depth for strength) to

sqrt(2)N (for a hypothetical 45 degree angle)

?

gweinberg
I don't think so. I don't think you need anywhere near a 45 degree angle, and
making the wall double thick won't really solve the fall over problem in the
first place.

Wouldn't it be easier to make with straight zig-zag sections than with wavy
curves?

I don't think you'd get the protection from lateral forces on the straight
sections. Just a little bit of curve transfers the cross force down the whole
curve.

The gist is, if i push on a brick in the middle of a flat part, the force has
to be resisted by the width of the single brick. but if i push on any part of
the curve, that's got to lift the adjacent next level up bricks as well, which
in turn have to lift the next level, and on and on.

It's been a long, long time since i studied static forces though.

 I don't remember you'd get the protection from lateral force on the square 
 sections. Just a little moment of curvature transfers the cross force out down the whole 
 curve. 

 The gist is, if i push on a brick in the center of a flat part, the force has 
 to be resisted by the width of the single brick. but if i push on any contribution of 
 the curve, that's got to lift the adjacent next level up brick as well, which 
 in turn have to face-lift the next level, and on and on. 

 It's been a farseeing, long fourth dimension since i studied static effect though.
