注浆对地基沉降量的影响关系

对于软粘土型路基,在车辆行驶时会产出不均匀沉降,沉降量可以通过分层总和法进行计算,地面接触压力、土体的自重应力、土层的压缩模量均是影响沉降的重要因素。地面的接触压力是外界影响因素,由于外界条件的限制而无法改变,而土体的自重应力、土层的压缩模量均可以通过注浆来改变,注浆后,土体自重和压缩模量将会提高,通过力学分析,得出一个注浆对地基沉降量的影响关系,可供设计与施工参考。

The Influence of Grouting on Foundation Settlement

For soft clay roadbed, the non-uniform settlement will occur when the vehicle is running, settlement can be calculated through the layered summation method, the ground contact pressure, the soil gravity stress, soil compression modulus are the important factors influencing the settlement. The ground contact pressure is the external influencing factors, due to the limitation of the external conditions, it could not be changed, but the soil gravity stress, soil compression modulus all can through the grouting to be changed, after grouting, the soil self-respect and compression modulus will increase, this paper, by means of mechanics analysis, gets a relationship between grouting and the soil settlement, which can be refered to design and construction.
