Foundation pile vertical compressive static load test method
The invention discloses a foundation pile vertical compressive static load test method. The foundation pile vertical compressive static load test method comprises the following steps that (1), a pile head is treated, specifically, firstly a loose broken layer and low-strength concrete at the top of a concrete pile head are chiseled off to expose main reinforcements, the pile head is washed clean, and then a pile cap is poured; (2), equipment is installed, specifically, a settlement measuring device, a pressure measuring device, a loading device and a counter-force device are installed, the loading device selects one or more oil jacks to be connected in parallel for synchronous loading, and the counter-force device selects any one of an anchor pile counter-force device, a ballasting platform counter-force device, an anchor pile ballasting combined counter-force device and a ground anchor counter-force device; (3), loading and unloading step by step are carried out; and (4), data are recorded and analyzed. According to the foundation pile vertical compressive static load test method, the efficiency and accuracy of the foundation pile vertical compressive static load test can be remarkably improved, and the measurement requirement is met.
本发明公开了一种基桩竖向抗压静载荷试验方法，包括以下步骤：1)桩头处理：混凝土桩桩头先凿掉桩顶部的松散破碎层和低强度混凝土，露出主筋，冲洗干净桩头后再浇筑桩帽；2)设备安装：安装沉降测量装置、压力测量装置、加载装置、反力装置，其中加载装置选用一台或多台油压千斤顶并联同步加载，反力装置选用锚桩反力装置、压重平台反力装置、锚桩压重联合反力装置、地锚反力装置中的任意一种；3)逐级加载和卸载：4)数据记录与分析。本发明提供的基桩竖向抗压静载荷试验方法，能够显著提高基桩竖向抗压静载荷试验的效率和精准度，满足测量需要。
