Method for estimating internal stress of pile body of concrete pile
The invention discloses a concrete pile body internal stress estimation method, belongs to the technical field of pile foundation detection, and can solve the problems of high test cost and low test efficiency of an existing foundation pile body internal stress test method. The method comprises the steps that S1, stratum distribution within the concrete pile length range, pile side friction resistance of all strata and concrete elasticity modulus are determined according to geological exploration data of a construction area; s2, a single-pile vertical compression resistance static load test is conducted on the concrete pile, a settlement curve between the loaded load and the pile top settlement amount and between the loaded load and the pile end settlement amount is determined, and the average internal stress of a pile body of the concrete pile is determined according to the settlement curve and the concrete elasticity modulus; and S3, according to the average internal stress of the pile body and the pile side friction resistance of each stratum, the internal stress of the section of the pile body of the concrete pile on each stratum interface is determined. The method is used for estimating the internal stress of the concrete pile body.
本发明公开了一种混凝土桩桩身内应力估算方法，属于桩基检测技术领域，能够解决现有基桩桩身内力测试方法试验成本高且试验效率低的问题。所述方法包括：S1、根据施工区域的地勘资料确定混凝土桩桩长范围内的地层分布、各地层的桩侧摩阻力和混凝土弹性模量；S2、对混凝土桩进行单桩竖向抗压静载试验，确定加载载荷与桩顶沉降量、桩端沉降量之间的沉降曲线，并根据沉降曲线和混凝土弹性模量确定混凝土桩的桩身平均内应力；S3、根据桩身平均内应力和各地层的桩侧摩阻力，确定混凝土桩在各地层分界面上的桩身截面内应力。本发明用于混凝土桩桩身内应力的估算。
