中文摘要 | 構造建築物時,必須考慮地耐力是否達要求,除了一般考慮的強度因素之外,地 盤的變形也同樣重要。本文主要目的在於藉由一設計不當之工程案例,從不同角度探討大 量沉陷發生的可能原因,並針對發生原因提出補救措施。研究結果發現,樁基礎並不是基礎 工程的萬靈丹,在某些地質條件下,採用樁基礎反而可能引發地耐力不足的問題;工程問題 的解決,亦須從發生原因及影響因素著手,採取補救措施。地中梁的主要功能在減低側向變 形造成土壤補充導致的地表沉陷量,並不能真正解決本基地的工程問題。建議本案例應該針 對厚黏土層的壓密沉陷量加以改善。 |
英文摘要 | When the structure are to be constructured, one has to consider whether the earth resistance is attained the requirement. Besides the strength factor is generally to be thought about in order to decide the earth resistance, the deformation of earth stratum is also very important. The main purpose of this paper is to study the possible reason of occuring big settlement with different thinking by an engineering case which was free of correct design and is focused on the occuring reason for previding means to save the situation. The present study indicates that pile foundation is not a panacea of foundation engineering. At some geological conditions, the earth resistance maybe not enough if the pile foundation is adopted. In order to solve the engineering problem, both the occuring reason and the influence factor should be considered and then one offers the corrective method, The main function of earth beam is to reduce the side deformation produced soils to be filled to induce the settlement of surface ground. However, the application of earth beam in this case can not completely solve this engineering problem. The consolidation settlement of the clayey stratum with large thickness should be suggested to aim directly at improvement for this engineering case. |
