已知两个等差数列\(\{a _{n} \}\)，\(\{b _{n} \}\)，其中\(a _{1} =1\)，\(b _{1} =6\)，\(b _{3} =0\)，记\(\{a _{n} \}\)前\(n\)项和为\(T _{n}\)，\(T _{n} = \dfrac {n^{2}}{2} + \dfrac {n}{2}\)．
\((1)\)求数列\(\{a _{n} \}\)与\(\{b _{n} \}\)的通项公式；
\((2)\)记\(c _{n} =a _{n} +b _{n}\)，设\(S _{n} =|c _{1} |+|c _{2} |+|c _{3} |+…|c _{n} |\)，求\(S _{n}\)．
