| 摘 要： | 加固地基是增强地基抗震性能的一种行之有效的方法。加固地基可提高地基抗液化能力，改善地基土的动力特性，减轻砂土地基的液化势；通过对地基土产生预震效应，提高了加固地基整体的强度、刚度和稳定性。对震害严重的厚冲积层或厚软土层，用高压喷射注浆法进行加固处理有其独特的优越性。

| Abstract: | Strengthening of ground is an effective measure to improve seismic behavior of the ground. The strengthening of ground can be used to raise its liquefaction resistant ability,, improve its dynamic behaviour and reduce liquefection potential of sand ground. Pre-shock of ground is beneficial to integral strength, stiffness and stability of the ground. Jet grouting with high pressure is of particular advantage to strengthening of the ground in thick alluvion and soft soil vulnerable to seismic damage. |
