珠江三角洲软土分布深厚且工程性质较差,其成因是受内海岸浪潮及潮汐水动力作用逐渐淤积而成,属第四纪沉积物。在公路建设中,由于软基处治工程量巨大,其方案的选取成为控制工程造价的关键。结合广州东沙至新联高速公路和试验路段实际,从工程地质、工程造价以及工期控制等多方面因素考虑,对多种软基处理方案分别进行比较与选定,并深入探讨了选取这些处治方案的依据,确定了试验路段的监控措施。
The soft foundation in the ZhuJiang delta plain is very deep and has a sort engineering properties and it formed Because of the inclosed coast erosion and the tide.Due to the high cost,the election of the treatment has became the key of the whole work.Based on the analysis of the engineering geology,cost and work while,it got the matched treatment and monitor mode for the test way of the highway from Dongsha to Xinlian.
