Proposed Mechanically Stablized Earth (MSE) Wall
Adhoc Name: Prop. MSE
Description: Proposed Mechanically Stablized Earth (MSE) Wall
Phase 1 Design (driven by adhocs only)
Phase 2 Design (driven by adhocs and profiles)
* Note: See also the Minimum Detour Width options.
ADHOC DESCRIPTIONS
“Wall Foreslope” - Slope in a Rise:Run format of the ground line connecting the shoulder to the top of the MSE wall. Be sure to include the colon between the numbers. Note this will vary if a bottom of footing profile is assigned for the MSE wall.
“Wall Batter” - Slope in a Rise:Run format of the outside face of the MSE wall. Be sure to include the colon between the numbers.
“Leveling Pad Depth” - Thickness in master units of the leveling pad used at the base of the MSE Wall existing ground.
“Wall Lift Height” - Thickness in master units of each MSE Wall lift. This number MUST be greater than zero.
“Set Back Width” - Minimum required horizontal distance measured from the base of the leveling pad to the daylight of existing ground. This number MUST be greater than zero. Note, the use of a bottom of footing profile may cause this value to fail. In the event the minimum setback width is not met by the use of a profile, a warning message will be drawn indicating such.
“Wall Width Factor” - Multiplied by the wall height this factor will determine the overall width of the MSE wall.
“Additional Exc Width” - Distance in master units to extend the width of the MSE wall.
“Min Reinforcement Length” - If greater than zero, the width of the reinforced volume will either be “_d_MSEWallWidthFactor” x “Wall Height” or “_d_MSEMinReinfLength”, whichever is greater.
“Wall Excavation Slope” - Slope in a Rise:Run format of the existing unsuitable line connecting to the existing ground line for the MSE Wall. Be sure to include the colon between the numbers.
“Embedment Depth” - Minimum depth below existing ground measured to the bottom of the MSE wall lifts. This does NOT include the depth of the leveling pad. This number MUST be greater than zero. Note, the use of a bottom of footing profile may cause this value to fail. In the event the minimum embedment depth is not met by the use of a profile, a warning message will be drawn indicating such.
“Bottom Footing Profile Name” - Specify the name of the proposed profile associated with the Phase 2 Design of the MSE wall.
IMPORTANT: Set this to “none” until the phase 2 chain and profile have been established using Cross Section Reports and COGO. In the phase 2 design the user MUST specify the correct COGO profile name to this adhoc. Refer to the FHWA Knucklehead's Guide for further explanation.
“Wall Chain Name” - Specify the name of the proposed chain associated with the Phase 2 Design of the MSE wall.
IMPORTANT: Set this to “none” until the phase 2 chain and profile have been established using Cross Section Reports and COGO. In the phase 2 design the user MUST specify the correct COGO profile name to this adhoc. Refer to the FHWA Knucklehead's Guide for further explanation.
“UNLOCK Wall Foreslope” - When designing a phase 2 wall using a chain and profile, the user may elect to have all wall lifts the same thickness including the top lift. To achieve this set this adhoc to Y (Yes). This will force the top lift to be the same thickness as the other lifts and ultimately vary the wall foreslope.
