求翻译：根据数据点分布图来看，防波堤的水平残余位移与液化度成一线性衰减关系，可用线性关系式（6-2）来拟合，由于结构的水平对称，衰减梯度较大，表明孔隙水压力对水平位移的影响很大；残余沉降与液化度成线性衰减关系，可用线性关系式（6-3）来拟合。公式的限制条件在E1>0.5。是什么意思？

Looked according to the data point distribution map that, the breakwater level remaining displacement and the degree of liquefaction become linear weaken relations, the available linear relationship (6-2) fits, because the structure level is symmetrical, weakens the gradient to be big, indicated the

According to the distribution of data points, levels of residual displacement of the breakwater and liquid into a linear attenuation relationship, using linear relations (6-2) to fit, because the horizontal symmetry, attenuation of gradient, showed that pore water pressure on the horizontal displace
