The invention relates to a detection method for a novel pile foundation bearing capacity. The detection method comprises the following steps that S1, a plurality of engineering piles are selected around a to-be-detected pile foundation to serve as anchor piles; S2, selecting at least two circles of anchor piles around the pile foundation to be measured; S3, a jack is installed on the to-be-detected pile foundation, a reaction frame is installed on the jack, the jack is connected with the reaction frame, and the anchor pile on the outermost circle is connected with the reaction frame; S4, the jacks are loaded step by step, each stage of loading is kept for a certain period of time, and pile foundation settlement data of each stage of loading are recorded until the anchor pile on outermost circle is close to the anti-pulling limit capacity; S5, the anchor piles are connected with the reaction frame circle by circle from the outermost circle to the inner circle, and each time when one circle of anchor piles are connected, the jacks continues to conduct step-by-step loading, and each stage of loading is kept for a certain period of time; and S6, after the anchor pile on the innermost circle is connected with the reaction frame, step-by-step loading is continued until the load specified by the test is reached. The detection method has the effects of improving the stability and safety of pile foundation bearing detection work and improving the accuracy of detection data.
本申请涉及一种新型桩基承载能力的检测方法，其包括以下步骤：S1：在待测桩基周围选择多根工程桩作为锚桩；S2：在待测桩基周围选择至少两圈锚桩；S3：在待测桩基上安装千斤顶，并在千斤顶上安装反力架，将千斤顶与反力架连接，并将最外圈的锚桩与反力架连接；S4：千斤顶逐级加载，每级加载保持一定时间，记录每级加载的桩基沉降数据，直至最外圈锚桩接近抗拔极限能力；S5：将锚桩从最外圈向内圈逐圈与反力架连接，每连接一圈锚桩，便使千斤顶继续逐级加载并保持一定时间；S6：在最内圈的锚桩与反力架连接后，继续逐级加载，直至达到试验所规定的荷载。本申请具有提高桩基承载检测工作的稳定性和安全性，以及提高检测数据的准确性的效果。
