Looking for experienced rock mechanics/geotechnical engineers with concreste structure experience. Check attachements before bidding A 2.50 × 2.50 m reinforced-concrete slab is placed directly on a rockfill surface (the downstream of a dam) inclined at 42°. The slab is subjected to a normal force and a downslope in-plane shear force from the structural model (components normal to plane and along slope), plus a small overturning moment. Interface friction is limited (φ = 28°- to be discussed further), so friction alone is not sufficient; stability is ensured by rock anchors installed perpendicular to the slope, providing normal clamping force. Anchors are Ø40/20 mm hollow steel, 6 m length as predimensioned, with field tests up to 25t and measured elongations/residual set. Design is governed by sliding, while overturning and bearing are secondary checks. Step 1 – Anchor design (global stability) Dimension the anchors (number + working load) so that: The system satisfies the required sliding safety factor under the resultant downslope action. Each anchor is verified for: steel tensile capacity, bond capacity in rock for the available length, realistic lock-off force considering seating / residual set from tests. Output: required normal clamping force from anchors, anchor load per piece, and confirmation the Ø40–6 m anchors are adequate. Step 2 – Slab design (structural capacity) Dimension the slab so it can transfer anchor forces to the rock: Determine minimum thickness for global bending and local effects near anchors. Provide reinforcement for: bending, local anchorage/plate zone (splitting, bursting), crack control. Verify local bearing under anchor plates and confirm no uplift (eccentricity within base). Output: slab thickness + rebar layout + local detailing around anchors.

Hi, I will perform a full anchored-slab stability and structural design in line with geotechnical and concrete standards. This includes sliding safety verification, anchor force demand, lock-off realism from test data, and checks for steel and bond capacity. I will then design the slab to safely transfer anchor loads, covering bending, local bearing, bursting, crack control, and uplift limits. Deliverables will include calculations, assumptions, and clear reinforcement and detailing drawings. Regards, Soas
