System and method for detecting horizontal bearing capacity of pile foundation
The invention relates to a system for detecting horizontal bearing capacity of a pile foundation. The system comprises a test pile with two half pile structures, wherein a counter-force loading deviceis mounted between pile tops of the two half piles, and a pressure device for providing horizontal load is mounted in the counter-force loading device and comprises a jack; the counter-force loadingdevice is used for performing multi-stage loading on the two half piles of the test pile under the action of the horizontal load provided by the pressure device, and the half piles are enabled to be inclined to soil mass on two sides respectively and deform; and two-way horizontal displacement meters used for measuring degree of deviation of the two half piles towards two sides are mounted betweenthe two half piles from top to bottom at certain intervals. According to the system, by determining a characteristic value of horizontal bearing capacity of a single pile and an interaction relationship of the pile and soil, basis is provided for design of the horizontal bearing capacity of the pile foundation, and safety of a laterally loaded pile is guaranteed. When the counter-force loading device is pressed from the middle, the half piles on two sides can be pressurized respectively, that is, horizontal bearing capacity of two piles are detected simultaneously, and the system for detecting the horizontal bearing capacity of the pile foundation has relatively high popularization value.
本发明涉及一种桩基水平承载力检测系统，包括两个半桩结构的试验桩，所述的两个半桩的桩顶之间安装有一个反力加载装置，所述的反力加载装置中安装有提供水平向荷载的加压装置，加压装置由千斤顶组成；反力加载装置用于在加压装置提供的水平荷载的作用下对试验桩的两个半桩分级加载，使半桩分别向两边土体倾斜变形；并在两个半桩之间自上而下每隔一段距离安装用于测量两个半桩向两边偏移的程度的双向水平位移计。本发明通过确定单桩水平承载力特征值和桩土相互作用关系，为基桩水平承载力设计提供依据，保证水平受荷桩的安全。反力加载装置从中间加压时，可分别对两边半桩施压，相当于同时检测两根桩的水平承载力，本检测装置有较高的推广价值。
