经动测捡测，发现的疑问的工程桩，经静压验证，在最大试验荷载下，疑问桩的

After dynamic testing, the suspected engineering piles were discovered and verified by static pressure. Under the maximum test load, the core of 50% of the pile tip of the suspected piles was block-columnar, which did not reach the limit end resistance, which has great potential; The core of 20% of the pile tip is broken to block, which is close to the limit end resistance, but 22.7% higher than the value calculated by the specification; 10% of the pile tip has a weak layer in the rock mass and is damaged by punching shear; 20% of the engineering pile The construction quality problems were treated as waste piles.

After dynamic testing and testing, found the project pile of doubt, verified by static pressure, under the maximum test load, the core of 50% of the pile of doubt is block-pillar, did not reach the limit end resistance, with greater potential; It is fragmented to block, which is close to the limit end resistance, but is 22.7% higher than the standard calculation value, 10% of the rock body at the end of the pile is clamped with weak layers that are cut and destroyed, and 20% of the piles are treated as waste piles due to construction quality problems.

According to the dynamic test and static pressure verification, 50% of the core at the pile tip of the suspected pile is massive to columnar under the maximum test load, which does not reach the ultimate end resistance, so it has great potential; 20% of the core at the pile end is fragmentary to massive, which is close to the ultimate end resistance, but 22.7% higher than the calculation value in the specification; 10% of the rock mass at the pile end is mixed with weak layer, which is destroyed by punching and shearing; 20 %Due to the construction quality problems, the engineering piles are abandoned.<br>
