我们在陕西关中地区,结合生产任务,利用16个孔(共1284个测点,总贯入深度单双桥探头各为193米)进行了静力触探单双桥探头p_s值和q_c值相关关系的对比试验,建立了相应的回归方程,现简介如下。一、试验条件及对比分析的原则 1.本次对比试验分别采用带7厘米长摩擦筒的单桥探头,以及一机部华中勘测大队的摩擦筒紧靠锥头的双桥探头,其锥底直径和截面积均为43.7毫米和15平方厘米; 2.测试仪器采用YJD-1型电阻应变仪,
In the Guanzhong area of Shaanxi Province, we used 16 holes (1 284 measuring points and 193 meters for the total penetration depth of single and double bridge probes respectively) in conjunction with the production task to correlate the p_s value and the q_c value of the static single probe and the double bridge probe. The comparative test of the relationship establishes the corresponding regression equation, which is summarized below. First, the experimental conditions and the principle of comparative analysis 1. This comparison test uses a single-bridge probe with a 7-cm long friction cylinder, and a double-bridge probe with a friction cylinder close to the cone head of a Central China Survey Brigade. Diameter and cross-sectional area are 43.7mm and 15cm2; 2. The test instrument adopts YJD-1 resistance strain gauge,
