选择合适的勘探手段和勘探技术,是提高勘探成果设计质量的关键。也可达到快速、可靠、经济地提供成果的目的;定量测定应力历史对粘性土压缩特性的影响,选择能考虑这一特性的沉降估算方法,使沉降量估算成果更符合实际,方案选择更合理;针对不同施工工期,结合高速公路工程实际,采取优化设计地基处理方法。
Choosing the right exploration method and exploration technique is the key to improve the design quality of the exploration result. But also to achieve the purpose of providing results quickly, reliably and economically; quantitatively determine the influence of stress history on the compressibility of clay; select the settlement estimation method which can consider this characteristic; make the estimation of settlement amount more realistic and the scheme selection more reasonable According to the different construction period, combined with the actual highway engineering, to optimize the design of ground treatment methods.
