When it comes to the calculation of cantilever retaining wall, the relevant architects are still relatively unfamiliar. What are the basic formulas commonly used in the calculation of cantilever retaining wall? The following is the basic content of cantilever retaining wall calculation compiled by Zhong Da Consulting for builders, with the specific contents as follows:

Zhong Da consulted Bian Xiao to sort out the relevant contents and the calculation contents of cantilever retaining wall:

Zhong Da Consulting combed the contents of relevant calculation formulas, mainly including:

Calculation of (1) earth pressure

1. Vehicle load conversion is based on the formula in Table 3-2-6, including

h0 = 200.00/γ[ 13.0+0.577(H+2a)]

= 200.00/( 18*( 13+0.577*(5.5+2*0))

= 0.687m2 Calculate the earth pressure with Rankine formula (β=0).

Ka=0.27 1 σ0=γh0Ka

= 18*0.687*0.27 1

=3.35 1 kPa

σH =γ(h0+H)Ka

= 18.0*(0.687+5.5)*0.27 1

=30. 180 KPa According to formulas (3-6- 1) and (3-6-4), the earth pressure e and the moment arm y of the whole wall are e =1/2γ H2ka (1+2h0/h).

=0.5* 18*5.5*5.5*0.27 1*( 1+2*0.687/5.5)

= 92.2 1 1kn y =(3h 0+H)H/3(2h 0+H)= 2.0 17m

Based on the above information, the main process of cantilever retaining wall construction generally includes:

Measuring and setting out → Foundation pit excavation → Foundation pit treatment and gravel cushion → Foundation reinforcement processing and formwork construction → Setting settlement joints → Foundation concrete pouring and maintenance → First floor wall reinforcement processing and installation and formwork construction → First floor wall concrete pouring and maintenance → Backfilling, drainage holes and filter layer → Second floor wall reinforcement installation and formwork construction → Second floor wall concrete pouring and maintenance → Backfilling drainage holes and filter layer → coping.
