In this study, the SIP (Soil-cement Injected precast Pile) method among the Low-vibration & Low-noise pile driving methods was decided into study compensation. Ground vibrations by the SIP methods step by step divide and were analyzed. Quantitative response values and ground vibration equations with reliability were presented from findings of this study. Also, vibration responses that are occurred by the SIP method of construction were compared as quantitative with vibration responses by general method of construction that are presented in existent study. Ground vibration values by the SIP method correspond to level of 17 ~ 57% of values that are assumed by the Attewell & Famer's equation, respectively, and these result compares in reliability 50% and separated distance 10 ~ 50 m. Also, those values were analyzed that correspond to level of 14 ~ 96% of ground vibration values by the Prof. Park's equation, respectively. Construction limit extents, separation distances from vibration occurs position, were presented that can satisfy domestic criteria for vibration control for the SIP methods. Those presented in this paper were divided newly according to reliability.

Construction equipment noise has caused much annoyance for a number of dwellers in nearby construction field and has become a very serious issure in our living environment. Therefore, in our country, a practical solution and a better method of reducing construction equipment noise are highly required in construction field. Practical solutions for the construction equipment noise, however, are very difficult because of the poorness of basic data and insufficiency of the existing research. Especially, in order to establish the sound insulation plan about pilling works noise with high sound pressure level and impactive, a real situation of sound characteristics about the noise of pilling works in foundation work demands more detail investigation. In this point, this study attempts to survey the characteristics of attenuation and propagation of construction equipment noise in pilling work using SIP(soil-cement injected precast pile) method with casing. And this study intends to get the basic data for establishment of a standard about construction noise.

Construction equipment noise has caused much annoyance for a number of dwellers in nearby construction field and it has become a very serious issue in our living environment. Therefore, in our country, a practical solution and a better method of reducing construction equipment noise are highly required in construction field. Practical solutions for the construction equipment noise, however, are very difficult to obtain, because of the lack of basic data and insufficient research works. Especially, in order to establish a successful sound isolation plan for piling work noise, which has high sound pressure level, the characteristics of the impact noise should be closely monitored and analyzed. This study attempts to survey the characteristics of attenuation and propagation of construction equipment noise in piling work by SIP(soilcement injected precast pile) method. In addition, this study intends to get the basic data to establish a standard about construction noise.

The SIP method developed by low noise-vibration from Japan is appropriate to the construction at urban area. However, this method has been misused as a pre-driiled driven pile method in Korea. Hence, Korea Expressway Corporation proposed 'Design & Construction Guideline for the SIP Method' following the original concept of the SIP method at 2004 and 2006. Also construction guideline of another auger-drilled piles were introduced.

말뚝기초는 국내에서 가장 많이 사용되고 있는 기초형식 중의 하나로서 상부 구조물의 하중을 하부의 단단한 지반에 전달시키거나 흙과 말뚝의 접촉면에서 발생하는 마찰저항을 이용하여 구조물을 안전하게 지지하도록 사용되고 있다. 그러나 말뚝공법은 작업절차가 복잡하고 세심한 주의를 필요로 하므로 경험이 부족한 기술자의 경우 공사관리에 큰 어려움을 겪게된다. 특히, 파일 시공단계에서의 문제점에 직면하게 되면 계량화된 분석에 의존하기보다는 항타기사나 작업반장의 경험에 의한 직관만으로 결정되는 경우가 많아 품질관리에 큰 어려움을 겪고 있는 실정이다. 이러한 필요성에 의해 본 논문은 실제 현장에서의 충분한 사례분석을 통한 파일공사의 단계별 문제점 및 관리요인 분석을 통해 개선 모델을 제시하고자 한다.

본 연구에서는 기존의 PC말뚝과 PHC말뚝의 시공성과 지지력에 대한 비교확인 시험의 결과를 근거로 하여 PHC말뚝의 시공상의 장점, 특성 및 경제성을 파악하였으며, SIP공법에 의하여 PHC말뚝을 사용시 기존 PC말뚝이나 강관말뚝보다 경제성이 우수함을 확인하였다. 또한 PHC말뚝은 압축강도와 지지혁이 기존 PC말뚝보다 높을 뿐만아니라 강관말뚝과 같이 용접이음이 가능하고 말뚝의 심도가 깊은 경우에도 강관말뚝과의 대체시공이 가능하여 PHC말뚝의 성능을 극대화할 수 있는 적절한 항타장비를 사용하는 경우에는 혁신적인 원가절감이 가능함을 확인할 수 있다.

본 연구에서는 국내 최근 SIP(Soil-Cement Injected Precast Pile) 공법의 문제점과 그 개선책에 대하여 현장재하시험 결과로부터 하중-침하량곡선과 지지력 특성을 이용하여 고찰하였다. 재하시험결과 전체침하량에 대한 탄성 및 소성침하량은 일정한 경향성을 갖으며, 이러한 경향성과 재하시험으로부터 결정한 지지력을 이용한 경험적인 차트가 SIP 설계에서 이용될 수 있다. 지지층의 지질조건이 화강암류를 갖는 국내 지역에서 N값을 이용한 SIP 설계는 매우 보수적인 결과를 보이고 있다. 반면 지지층의 지질학적 조건이 불리한 경우 불안정한 결과를 보일 수 있다. 또한, 말뚝선단에서 N값을 수정한 Meyerhof의 지지력식이 N값이 50으로 한정되고 선단지지력을 20NA$_p$으로 간주한 최근의 설계보다 적절하다는 것을 확인할 수 있었다. 이러한 결과들은 수정된 설계법이 말뚝의 지지력을 말뚝재료의 허용하중까지 이용하기 때문에 과거보다 경제적임을 시사한다.
