Double-steel-sleeve batholith load plate test system and double-steel-sleeve batholith load plate test method
The invention belongs to the technical field of geotechnical engineering, and particularly discloses a batholith load plate test system and method with double steel sleeves. The heaped load applying module is arranged on the pile top and applies a preset load to the pile top of the cast-in-situ bored pile; the external force eliminating module is arranged on the outer side of the cast-in-situ bored pile body in a sleeving mode and used for eliminating the frictional resistance influence of a soil body on the side wall of the cast-in-situ bored pile body The monitoring module is used for monitoring settlement displacement and stress of the cast-in-situ bored pile under the loading action of the pile loading applying module; and the control module is used for judging the bearing capacity of the deep rock mass foundation according to the monitoring data of the monitoring module. Lateral pressure of a soil body on a pile body can be effectively isolated, side wall friction resistance of the pile body can be eliminated, a real load applied to the pile bottom is ensured, the real bearing capacity of a deep foundation rock body can be accurately measured, test data are more accurate, influences of pile foundation side friction resistance are avoided, and therefore the accuracy and reliability of a test result are improved.
本发明属于岩土工程技术领域，并具体公开了一种双钢套管的岩基载荷板试验系统及方法。包括：设于桩顶并对钻孔灌注桩桩顶施加预设载荷的堆载施加模块；套设于钻孔灌注桩桩身外侧用于消除土体对钻孔灌注桩桩身侧壁摩阻力影响的外力消除模块；用于监测钻孔灌注桩在所述堆载施加模块的加载作用下的沉降位移和受力的监测模块；以及用于根据所述监测模块的监测数据判断深层岩体地基承载力的控制模块。本发明能够有效隔离土体对桩身的侧向压力，消除桩身的侧壁摩阻力，确保施加在桩底的真实载荷，可以准确地测量深部地基岩体的真实承载力，使得试验数据更加精确，没有桩基侧摩阻的影响，从而提高了试验结果的准确性和可靠性。
