中文摘要:由于软土地基的承载能力低、承受荷载后变形大，在建设中若有疏忽，将会导致建筑物开裂，甚至产生损坏和失稳，因此软土地基的研究工作显得尤为重要。
软土地基的后期沉降监测是一项十分重要而有意义的工作，通过后期沉降的监测结果的分析可以实现对建筑物的稳定性进行评估，可以进一步了解软土地基的特性，并完善软土地基的处理方法。本文将借助ANSYS进行结构计算来得出相关理论沉降量，绘制成PTS曲线。PTS曲线是荷载－时间－沉降曲线，PTS曲线生成系统是基于Excel与AutoCAD软件的二次开发功能编制成的荷载一时间－沉降曲线生成系统，系统针对沉降监测数据的自动读取与参数化生成PTS曲线进行了重点实现，解决了大量沉降板监测数据PTS曲线生成的繁杂问题。文章将通过这种方法实现对强夯法软土地基处理方法的系统分析，进一步评估强夯法软土地基处理的方法。最终通过研究软土工程特性，逐步认识他们对工程的反应和危害的规律，以便采取有针对性的技术措施，使软土地区的建设工程达到技术先进、经济合理和使用安全的目的。39068

Abstract:
Soft soil is silt, high natural water content, high compressibility, low bearing capacity of saturated clay, silt etc. In China, the distribution of soft soil area is very wide, especially in the coastal area. Due to the bearing capacity of soft soil foundation is low, and large deformation after load, in the construction, if there is negligence, will lead to cracks, even damage and instability, so the research work of the soft soil foundation is very important.
The soft soil foundation settlement monitoring is a very important and meaningful work, through the analysis of monitoring results of the late settlement can achieve stability of the structure of the evaluation, we can further understand the characteristics of the soft soil foundation, and improve the treatment method of soft soil subgrade. This paper will use ANSYS structure calculated settlement theory, draw PTS curve. The PTS curve is the load time settlement curve, PTS curve generation system is Excel and AutoCAD two software development function compiled into the load time settlement curve generation system based on the system, aiming at automatic reading and parametric PTS curve were mainly focus on the implementation of the settlement monitoring data, to solve a lot of problems in complex settlement monitoring the data generated by PTS curve. This will be achieved through this method dynamic analysis system processing method of soft soil foundation of strong, further evaluation method of dynamic compaction method in soft soil foundation treatment. Through the engineering characteristics of soft soil, they gradually realized on the engineering reaction and damage law, so as to take targeted measures, make construction engineering in soft soil area to advanced technology, reasonable economy and safety to use.
Keywords: soft soil foundation, dynamic compaction method, ANSYS finite element calculation, PTS curve generation system
