地质勘察中已广泛应用静力触探技术,该方法是将触探头按一定速率压入土中,原位量测其贯入阻力(包括锥尖阻力和侧壁摩阻力),由此估计天然地基的容许承载力、桩基容许承载力、判定砂土地基液化等。土的分布及其力学特征往往是十分复杂的,正如大家所熟知的,地质系统中常存在各种不确定(或不确知)因素和各种偶然因素。因而在贯入过程中,由于土层阻力变化,触探所得锥尖阻力和侧壁摩阻力随深度的变化曲线均呈现出不规则形态。曲线不规则也由于下列因素: 1.各深度上湿度、温度不同,原来的起始“零点”发生变化(或零点漂移)。 2.由于仪器灵敏度的限制,每一行程
Geological survey has been widely used static cone detection technology, the method is to touch the probe pressed into the soil at a rate, in-situ measurements of penetration resistance (including the cone tip resistance and sidewall friction), thus estimating the natural foundation The allowable bearing capacity, the allowable bearing capacity of pile foundation and the liquefaction of sand foundation. The distribution of soil and its mechanical characteristics are often very complicated. As we all know, there are always various uncertainties (or uncertainties) and various contingencies in the geological system. Therefore, during the penetration process, due to the change of soil resistance, the cone tip resistance and the frictional resistance of the sidewall with the depth curve showed irregular shape. Irregular curves also due to the following factors: 1. The depth of the different humidity, temperature, the original starting “zero” change (or zero drift). 2. Due to the sensitivity of the instrument, each stroke
