砖石古塔的地震“修复”及动力学特征初探

Disscusion of the Earthquake Renovation and the Dynamic Characteristic of Ancient Brick and Rock Pagoda

汇集了 4例震裂古塔震而复合的有关历史资料。分析认为可探索用人工激震方法对开裂古塔进行修复。从震害资料看出 ,砖石古塔在地震烈度 度以上时将出现破坏。研究了砖石古塔的结构特性 ,提出了对古塔自振周期的计算公式。指出这些研究对古塔的修复、加固及抗震性能评价 。

This paper has collected with four examples of historical Literature about the ancient pagoda that bursted from earthquake and then recovered by the another earthquake.It reveals people to can renovate bursted ancient pagoda by artificial vibration.The ancient brick and rock pagoda will be ruptured by over Ⅵ of seismic intensity.The paper studied the characteristic of structure of ancient brick and rock pagoda,proposed the formula of self vibration period for ancient pagoda.The results are beneficial for ancient pagoda's reclamation,strength and evaluation of earthquake resistant.
