| 摘 要： | 就砂井处理方法对地基土的扰动进行了初步试验研究，如现场的十字板，无侧限抗压强度和室内共振柱三轴试验，渗透试验，分析了砂井施工引起的土体力学性质变化，以及重塑剪切弹模和渗透系数随静置时间的变化规律，并根据连续介质损伤力学的相关理论，计算了施工引起的损伤比。

| Abstract: | A preliminary research on the effect of sand drainage construction on the disturbance of soil has been made. It includes in situ vane test, unconfined compression test, resonant column triaxial test and permeability test. Variation of mechanical characteristics, restructure of shear modulus and time dependent permeability of remolded soil have been analysed. The percetage of damage caused by construction has been calculated according to the related theory of continuous medium damage mechanics. |
