振動臺法實驗裝置試驗方法（干土法）

★充分?jǐn)嚢韬娓稍嚇樱词蛊漕w粒分離程度盡可能??；然后大致分成三份。測定并記錄空試筒質(zhì)量。

★用小鏟或漏斗將任一份試樣徐徐裝入試筒，并注意使顆粒分離程度?。ㄑb填宜使振畢密實后的試樣等于或略低于筒高的1/3）抹平試樣表面。然后可用橡皮錘或類似物敲擊幾次試筒壁，使試料下沉。

★放置合適的加重底板于試料表面，輕輕轉(zhuǎn)動幾下，使加重底板與試樣表面密合一致。卸下加重底板把手。

★將試筒固定于振動臺面上，裝上套筒，并與試筒緊密固定，將合適的加重塊置于加重底板上，其上部盡量不與套筒內(nèi)壁接觸。

★設(shè)定振動臺法試驗裝置在振動頻率50Hz下的垂直振動雙振幅為0.5mm；或在振動頻率60Hz下的垂直雙振幅為0.35mm。

振動試筒及試樣等，在50Hz下振動10min；在60Hz下振動8min。振畢卸去加重塊及加重底板。

★按本規(guī)程2-5步驟進(jìn)行二層、第三層試料振動壓實。但第三層振畢加重底板不再立即卸去。

★卸去套筒，然后檢查加重底板是否與試樣表面密合一致，即按壓加重底板邊緣，看其是否翹起，若翹起則宜在試驗報告中注明。

★將百分表架支桿插入每個試筒導(dǎo)向瓦套中；刷凈試筒頂沿面上及加重底板上位于試筒導(dǎo)向瓦兩側(cè)測量位置所積落的細(xì)粒土，并盡量避免將這些細(xì)粒土刷進(jìn)試筒內(nèi)，然后分別測讀并記錄試筒導(dǎo)向瓦每側(cè)試筒頂沿面（中線處）各三個百分表讀數(shù)，共12個讀數(shù)（其平均值即為終了百分表讀數(shù)Rf）。

★卸去加重底板，并從振動臺法試驗裝置面上卸下試筒。在此過程中，盡可能避免加重底板上及試筒沿面上落積的細(xì)粒土進(jìn)入試筒里。如這些細(xì)粒土質(zhì)量超過試樣總質(zhì)量的0.2%，應(yīng)測定其質(zhì)量并注明試驗報告中。

★在合適的臺稱上測定并記錄試筒及試樣總質(zhì)量，扣除空試筒質(zhì)量即為試樣質(zhì)量，或仔細(xì)地將試筒里試樣全部倒入已知質(zhì)量的盤中稱量。計算大干密度dmax。

★重復(fù)1-10步驟，直至獲得一致的大干密度值（好在2%內(nèi)）。如果發(fā)現(xiàn)產(chǎn)生過分的顆粒破碎或者是有棱角的石渣、堆石料或風(fēng)化弱巖石料，則宜盡量制備足夠數(shù)量代表性試樣，以避免單個試樣重復(fù)使用。;濕土法，結(jié)果整理、壓實指標(biāo)計算請參照相關(guān)規(guī)范。

Shaking table method experimental device test method (dry soil method)

★ Stir the sample thoroughly, even if the particle separation is as small as possible; then roughly divide it into three parts. Determine and record the mass of the empty test tube.

★ Use a spatula or funnel to slowly put any sample into the test tube, and pay attention to make the particle separation degree small (filling should be equal to or slightly lower than 1/3 of the height of the tube) The surface of the sample. Then, the test tube wall can be tapped several times with a rubber hammer or the like to sink the sample.

★ Place a suitable weighted base plate on the surface of the sample and gently turn it a few times to make the weighted base plate conform to the surface of the sample. Remove the weighted base handle.

★ Fix the test tube on the vibration table, install the sleeve, and fix it tightly with the test tube. Place the appropriate weight on the weighted base plate, and the upper part should not touch the inner wall of the sleeve as much as possible.

★ Set the vertical vibration double amplitude of the vibrating table test device at a vibration frequency of 50 Hz to 0.5 mm; or the vertical double amplitude at a vibration frequency of 60 Hz to be 0.35 mm.

The vibration test tube and the sample were vibrated at 50 Hz for 10 min; at 60 Hz for 8 min. After the vibration is removed, the weighting block is removed and the bottom plate is added.

★ Perform vibratory compaction of the second and third layers of samples according to steps 2-5 of this procedure. However, the third layer vibrating the base plate is no longer removed immediately.

★ Remove the sleeve and check whether the weighted bottom plate is in close contact with the surface of the sample. Press the edge of the bottom plate to see if it is lifted. If it is lifted, it should be noted in the test report.

★ Insert the dial indicator rod into each test tube guide sleeve; brush the fine-grained soil accumulated on the top surface of the test tube and on the weighted bottom plate at the measurement position on both sides of the test tube guide tile, and try to avoid These fine-grained soils are brushed into the test cylinders, and then each of the three dialect readings on the top surface of the test-tube (on the centerline) of each side of the test-tube guide is read and recorded, for a total of 12 readings (the average is the end) Dial indicator reading Rf).

★ Remove the weighted base plate and remove the test tube from the surface of the vibrating table test device. In this process, it is avoided as much as possible to increase the fine-grained soil deposited on the bottom plate and along the test tube into the test tube. If the quality of these fine-grained soil exceeds 0.2% of the total mass of the sample, the quality should be determined and indicated in the test report.

★ Determine and record the total mass of the test tube and the sample on a suitable table scale. Deduct the mass of the empty test tube to determine the mass of the sample, or carefully pour all the samples in the test tube into a known quality plate. Calculate the large dry density dmax.

★ Repeat steps 1-10 until a consistent large dry density value (better within 2%) is obtained. If excessive particle breakage or angular gravel, rockfill or weathered weak rock material is found, it is advisable to prepare a sufficient number of representative samples to avoid repeated use of the individual samples. Wet soil method, the results of finishing, compaction index calculation, please refer to the relevant specifications.
