| 中文摘要: |
| 针对大小鱼山北堤堤基范围地质条件复杂多变的特征，开展了围堤加固方案的研究。1）分析堤基具有软土深厚、局部发展有深槽的特点，概括地质特征。2）采用圆弧滑动法对不同地质特征的典型断面，尤其是深槽段进行稳定分析。3）提出结构方案的优化建议。研究结果表明：采用爆破挤淤地基加固方案处理含砂层的深厚软基是合理可行的，镇压棱体的范围和高程对结构优化有重要影响。优化方案可有效减少抛石量、降低工程造价。 |
| 英文摘要: |
| The reinforcing scheme of the seawall is studied because of the complex and changeable geological conditions of the foundation in the north levee of Da-xiao-yushan. 1）The characteristics of seawall foundation with deep soft soil and deep groove are analyzed，and the geological characteristics are summarized. 2）The stability of typical sections with different geological characteristics，especially deep groove sections are analyzed by the arc sliding method. 3）The optimization suggestions for structural schemes are proposed. The research results show that it is reasonable to use the blasting compaction foundation reinforcement scheme，and the range and elevation of the rock platforms have an important influence on structural optimization. The optimization scheme can effectively reduce the amount of rock and the cost. |
