"國內各項重大工程基於結構物的重要性及地質條件等因素之考量多採用樁基礎，其又由於風力或地震力之考量，除軸向承載力外，側向承載力亦是工程師設計時所考量之重要因素。本計畫首先旨在探討應用單樁側向承載力之新式連續性量測設備，即擬採用新的 SAA(Shake Accel Array)陣列式位移計，配合申請人已提出之分析方法，探討單樁之側向承載力行為。藉由此新式量測儀器之較高精確度，預期可更了解單樁受側向力作用之樁 /土互制行為。再者，擬探討樁帽之設置對群樁/土壤互制效應之影響。藉樁帽對群樁行為之影響研究，經本計劃提出之分析方法，除可與少數研究成果相互驗證外，亦可更了解群樁之整體效用，以及樁帽對群樁側向承載力之貢獻度，並可建議出樁帽與樁頭搭接處之受力-位移之關係式，提供爾後相關工程設計之參考。""Most of the import structures in Taiwan adopt pile foundations to support structures due to geological factors. Furthermore, in addition to axial capacity of pile, lateral pile capacity is another important factor for pile design by considering the effects from wind load and from seismic load. The purpose of this proposal is firstly aim to study the single pile lateral capacity by using the most updated measuring gages called ShakeAccelArray (SAA). SAA is a calibrated smart array which can be used to measure full 3D shape and 2-3D vibration using a compact array of MEMs sensors and proven Shape Tape/Shape Rope algorithms. A better understanding of pile lateral performance is expected by incorporating measurement results into the analytical method proposed by the author. In the second year, it is proposed to study the effect of pile cap on cap-pile group-soil interaction. Contribution of cap on pile group lateral capacity will be evaluated. Consequently, the load vs displacement relationship between cap and pile head will be studied by modelled as a possible non-linear spring in between each pile and cap. Stiffness of the spring will also be evaluated for future design reference. Results out of the study will also be verified from the available references."
