利用地面破坏现象评定地震烈度的研究

本文系统地介绍了聚乙烯改性沥青的室内试验研究结果。低密度聚乙烯具有较好的改性效果，改性后的沥青及其沸合料的路用性能皆比基础沥青的好。本文还就聚乙烯的改性机理作了初步探讨。

Research On Seismic Intensity Evaluation Using The Phenomena Of Ground Failure

In this paper,according to the damage information of many recent and historical strongearthquakes,we gave a minute discussion for seismil intensity evaluation using the phenomena ofground failure and summed up that the phenomena of ground failure have some distinctive good- points of the universality and the continuity of distribution,better relativety with seismicintensity,better conservation value than buildings damage and so on.
