土壤的剪切波速(V S ),是抗震设计的一个重要参数,但有关澳门土层的相关资料则十分稀少。研究的主要目的是根据近期野外测试的结果,探讨澳门土层的V S与标准贯入试验的打击锤数(N)的关系,并以简单之幂函数建立V S与N值的关系式。作为澳门轻轨交通系统之勘察计划,研究进行了五组下孔法(DH),地震波圆锥触探试验(S-CPT)以及标准贯入试验(SPT)的测试。根据试验结果所得的关系式估算剪切波速高于较澳门轻轨设计大纲的建议值,而使用另一有关澳门土层的数据库来验证新的关系式,亦可获得合理的决定系数。
土壤的剪切波速(V S ),是抗震設計的一箇重要參數,但有關澳門土層的相關資料則十分稀少。研究的主要目的是根據近期野外測試的結果,探討澳門土層的V S與標準貫入試驗的打擊錘數(N)的關繫,併以簡單之冪函數建立V S與N值的關繫式。作為澳門輕軌交通繫統之勘察計劃,研究進行瞭五組下孔法(DH),地震波圓錐觸探試驗(S-CPT)以及標準貫入試驗(SPT)的測試。根據試驗結果所得的關繫式估算剪切波速高于較澳門輕軌設計大綱的建議值,而使用另一有關澳門土層的數據庫來驗證新的關繫式,亦可穫得閤理的決定繫數。

Dynamic soil properties are important parameters for earthquake-resistant design. However, corresponding information is very scarce for Macau soils. This paper presents the preliminary correlation results between V S and SPT blow counts on Macau soils based on recent field tests obtained from the site investigation program for the design of the Macau Light Rapid Transit (LRT) project. Five pairs of Down-Hole (DH) and Seismic Cone Penetration Test (S-CPT) were performed at various locations to measure the shear wave velocity together with Standard Penetration Test(SPT) carried out in the corresponding boreholes. A preliminary correlation relationship of shear wave velocity(V S) and SPT blow counts(N) was also developed based on a power function. Compared with the Design Brief of LRT in which a preliminary correlation guideline is presented, this correlation, established based on the testing results, generally predicts higher shear wave velocity for soft to medium soft soils. Favorable coefficients of determination were also obtained for the newly established correlation evaluated with a different data set from an independent study for Macau soils.
