Abstract
銆?/p>
The authors analyzed using 7.0PB1 software for calculation of Lizheng deep
foundation pile anchor bracing design
锛?/p>
anchoring length by software designers will be calculated
artificially shortened after checking
锛?/p>
the overall stability of anti overturning stability checking and
basal heave calculation can meet standard requirements
锛?/p>
to meet the standard design requirements
锛?/p>
but the reason is deep the 7.0PB1 software foundation calculations did not reflect the bolt itself pullout
safety coefficient calculation
锛?/p>
anchor pullout safety coefficient does not meet the specification
requirements. From this problem
锛?/p>
some matters needing attention in the design of foundation pit
support are discussed.
