海滩地区软土路基瞬时沉降分析

软基瞬时沉降目前还没有很完善的计算方法，而海滩地区软土路基所处环境又较复杂，由于长期受潮汐影响，两旁一般都筑有围堰。结合厦门一滨海路基变形监测资料，对瞬时沉降进行了分析，在考虑围堰及潮汐等影响因素的情况下，建立了该类地区软基瞬时沉降的计算公式。由于该方法各计算参数都是由厦门地区软基变形实测资料而得出，故能较好地计算该地区软基瞬时沉降，而对其他类似地区也有一定的参考作用。

Analysis of soft foundation instant settlement in seaside areas

There is no perfect calculation method for soft foundation instant settlement at present. And the environment of the seaside soft foundation is very complicated. As the foundation is always affected by the tide,in general,there exist embankments in the two sides. The measurement data from a seaside road foundation treatment project in Xiamen are used to analyze instant settlement,on the condition of considering the influences of embankment. Finally the instant settlement calculation method is established. As the parameters about the method are obtained from the measurement data in Xiamen area,then it can calculate the soft foundation instant settlement very well there; in addition it also can be used for some other places in the similar conditions.
