The specific embodiment
A kind of solid shore as shown in Figure 1 wall-retaining structure is the assembly that is formed by guanovulite or rubble material in the solid shore cage that is assembled into after the ecological graticule mesh cutting, is a kind of flexible retaining structure of gravity.
Gu the main deformation place of shore barricade is at its wall body middle part, in order to reduce distortion, considered tilts to increase passive earth pressure or the suitable faulting of slab ends 5cm~10cm of metope when laying solid shore, upper strata cage 1 with suitable angle when design.When height is above greater than 6m, can adopt counterfort formula structure; Also can increase solid shore cage 1 step width, the high barricade that surpasses 4~5m of wall should use 1 conduct of the high solid shore cage of 0.5m basic.
Gu the backfill 3 behind the barricade body of wall of shore should adopt the granular materials that allows free draining, comprises the classification rubble that 5-30cm is thick, lays one deck fine sand pellet bed course thereafter, the optional one deck geotextiles 4 of being unable to sleep well in a new place when not having suitable natural materials.
Gu the buried depth of shore barricade should be according to landform, geology, current scour condition, and Stability Analysis of Structures and base stabilization requirement etc. are confirmed.Gu the basis of shore barricade should be arranged under the expection scour depth.Earthen foundation toe of wall buried depth should place the following 0.5-1.0m of scour depth, when riverbed undulating not at ordinary times, suggestion is provided with green shore pad protection-apron 2, length is scour depth 1.5-2.0 times.
Soil pressure is calculated with reference to " water conservancy project DESIGN OF RETAINING WALLS standard " and (SL379-2007) is calculated behind the wall, anti-ly inclines, need not consider during the antiskid stability calculation osmotic pressure behind the wall, also need not consider buoyancy.Safety factor should meet the related request of " water conservancy project DESIGN OF RETAINING WALLS standard "; Barricade on the soil matrix to consider along the antiskid of basal surface stable outside, also should adjust the stability against sliding of body of wall and base integral, the Sweden's arc method among the suggestion employing " Code for design of levee projects " is calculated.During base compressive stress checking computations, the eccentric distance e that general requirements is made a concerted effort 0In 1/3 scope at center, floor, maximum crushing stress σ Max<(σ 0) ((σ 0) be bearing capacity of foundation soil), σ Max/ σ MinCohesive soil 1.5~2.5, (requirement of traditional structure barricade is σ to sandy soil 2.0~3.0 m≤(σ 0), σ Max≤1.2 (σ 0).
