摘要
通过使用ANSYS中的PLANE42、CONTACT171和与之配套的TARGET169单元建立嵌岩灌注桩和土的相互作用二维模型,得到不同荷载作用下的桩顶沉降量并画出模拟所得到Q-S曲线.经过对工程实例的计算与实测对比分析,证明该理论可靠、方法简单,且具有较好的实用性.计算得到的Q-S曲线与实测的曲线非常吻合.
In this paper,a two dimensional model between the rock - socketed filling pile and the soil is established by using the PLANE42 CONTACT171 and TARGET169 in ANSYS. Then we can get different sedimentations under the condition of different loads and eventually draw the Q - S curve after calculation. Comparison between the results obtained by the proposed method and the measured data is made; and close agreement has been found. It is shown that the proposed method is theoretically reliable, simple in application and useful in practice.
