By the check - out, inspection and measurement to start construction the industrial art to this test pile with the examination between stake body mass and bearing power, made sure the stroke reasonable operation method drilling under the dissolved cavern geology term ; the pier foundation loading test expressed the lading and rub the lading that resistance drag a glazing for of relation, and to the borehole cast - in - place concrete pile in the karst terrain deliver with break the mechanism, the characteristic of bearing power, proceeding the spot test job of the full of result ; the test data expresses the stake side friction resistance to rises with a bat batch terminal friction resistance very important function, the of tip of pile resistance drag occupies the proportion very few
通過對本次試樁施工工藝的檢測和樁身質量及承載力的檢驗,確定了沖擊鉆在溶洞地質條件下的合理使用方法;基樁承載實驗表明了荷載與
摩擦
阻力之間的關系,並對巖溶地區的嵌巖灌注樁的荷載傳遞和破壞機理、承載力特性,進行了富有成果的現場測試工作;試驗數據表明樁側
摩阻和支盤端
阻起很重要的作用,樁端
阻力所佔比例甚少。這與設計樁基時的計算模式相差很大,承載力也較設計增加;使用力學數值分析方法和有限單元法,對鉆孔灌注樁樁端下的巖體強度和結構穩定性方面進行模擬計算和定量研究。
Secondly, we recommend the practical experiment of cast - in - place piles, including field solid and liquid qualification, experiment purpose, experiment project, experiment equipment, experiment process and the notice of experiment. thirdly, we processed and analyzed experimental daters, studied the rule of strength transferring, and studied the rule of strength transferring of check resistance and side of peg rub resistance, contrasting with common re - draw peg. at last, we advance some unfathomed problem and prospect foreground of cast - in - place piles
