工程桩完成后常用的检测方法除了钻取岩心、预埋管超声检测法以外,还有静载试验、高应变动力检测和低应变动力检测等方法。1.静载试验单桩的静载试验可分为抗压、抗拔和水平试验等。对于竖向抗压静载试验,其加载装置一般采用油压千斤顶,反力装置可为锚桩-反力架系统或压重平台。加载量值由并联于千斤顶油路中的精密压力表控制, After the engineering pile is completed, the common detection methods include the static core loading test, high-strain dynamic detection and low-strain dynamic detection, in addition to core drilling and ultrasonic testing of buried pipes. 1. Static Load Test Static load tests for single piles can be divided into compressive, pull-out and level tests. For the vertical compressive static load test, the loading device generally uses hydraulic jacks, and the reaction force device can be an anchor pile-reverse force system or a pressure-weighted platform. The load value is controlled by a precision pressure gauge connected in parallel to the jack oil circuit.
